Liverpool are one of the most successful clubs in English football history and have consistently competed for the top-spot with the likes of Manchester United to be crowned champions of England.
In recent history, the club has struggled to live up to their golden years of the 1970s when the Anfield club won two European and two UEFA Cups during the decade.
Undoubtedly, their team was made up of stars such as Kevin Keegan, Ray Clemence, Emlyn Hughes, and John Toshack among many other stars. However, since those heady days, the club has failed to deliver in the Premier League, as is yet to win one of the 24 editions to date.
For all of the wonderful players that have graced the hallowed Anfield turf, there have been some serious flops.
With that, we’ve put together a list of the 15 worst Liverpool signings of the Premier League era.
15 Andriy Voronin
The Ukrainian was signed on a free transfer by Rafael Benitez after a few decent seasons in the German Bundesliga. The ponytail-haired forward came to Anfield as the No. 10 which could be a reflection of how far the club had slipped since their glory days.
Voronin never really found his feet in England and although he scored a nice goal at Toulouse in a Champions League qualifier, the striker eventually left the club after two-and-a-half years in January 2010.
In total, the Ukrainian managed just six goals in 40 goals for the Reds and remarkably commanded a £1.4 million fee when he left Anfield for Dinamo Moscow on a permanent deal.
14 Bruno Cheyrou
Upon signing for the club, Frenchman Bruno Cheyrou was dubbed “the new Zidane” by manager Gerard Houllier, but unfortunately for the youngster, things didn't work out on Merseyside.
The then 24-year-old was expected to add goals and guile to the team from midfield, having scored 15 times for Lille before leaving the club in May 2002. However, it soon became clear the player was out of his depth in the Premier League.
Cheyrou never lived up to the hype and was considered physically weak for the English style of football. In his four years at the club, he only managed 48 games and has to go down as one of the most disappointing signings the club has made during the Premier League era.
13 Salif Diao
Midfielder Salif Diao was one of two Senegal stars who arrived at Anfield in 2002 after a successful World Cup in Japan and South Korea for the African side.
Liverpool legend Steven Gerrard revealed in his autobiography that “With Salif, I knew after a week of training that he wasn't going to be good enough.”
Although the midfielder was on the books of Liverpool for five years, in reality the player lasted just three seasons with the Reds before going out on loan to Birmingham City, Portsmouth and Stoke City before leaving for the latter permanently in 2007.
12 Sean Dundee
Sean Dundee joined the Merseyside club in July 1998 from German club Karlsruhe. Although the player was born in South Africa, his decent goal scoring spell in the Bundesliga allowed him to apply for a German passport with the potential of national service for his adopted country.
On joining Liverpool, he was restricted to just five appearances in all competitions without registering a goal before being sold back to Germany with VfB Stuttgart the following season. His time in England was ultimately disastrous for his career and never really re-found his goalscoring touch throughout the remainder of his career.
11 Fernando Morientes
A Spanish sensation with Real Madrid, Morientes’ £6.48m switch to Anfield had Kop fans thinking they’d made an excellent signing in 2005. Although the three-time Champions League winner came with pedigree, he returned to La Liga after just two mediocre seasons in the North west, scoring on just 15 occasions for the Reds.
Morientes was obviously a wonderful goalscorer in his career, especially at Real Madrid, but unfortunately for the Reds, they never got to see his true colors during his stay in Liverpool.
10 Erik Meijer
After relatively successful spells in Dutch and German football, Erik Meijer was signed by the English giants in July 1999 from Bayer Leverkusen. The Dutch international became somewhat of a cult hero at Anfield for his 'never say die attitude', but only managed two goals for the club - both against Hull City in a League Cup tie.
The striker joined Preston North End on loan but failed to score for the club that played in a lower division and was eventually offloaded to Hamburg in December 2000.
In total, the Dutchman only managed to play 26 times for Liverpool and although he will be remembered by fans, he surely has to go down as a poor singing for the club.
9 Fabio Borini
Fabop Borini was one of Brendan Rodgers' first Liverpool signings and an expensive one at £9.31 million from Serie A. Unfortunately for the striker, his Liverpool career never took off and he became another striker to fail to make the grade at the club during the Premier League era.
Borini was often overlooked for games and when he did manage to play, he offered little more than frustration for supporters and management alike. The striker played just 38 times, scoring just three times before signing a four-year contract with Sunderland in August 2015.
Josemi was new Liverpool manager Rafa Benítez's first signing when he joined the club in 2004, but this right-back from Malaga made just 16 starts in a year-and-a-half at Anfield before being sold back to Spain with Villarreal in a deal that saw another flop Jan Kromkamp join the club.
The right-back had built up a strong reputation in Spain but after a series of injuries and poor form, he couldn't dislodge Steve Finnan from the first-choice spot in the Liverpool line-up.
7 Alberto Aquilani
The Italian midfielder was bought for a fee of £14 million in 2009 as the replacement for Real Madrid bound Xabi Alonso. Injuries hampered the start to his Liverpool career and meant that the midfielder did not start a league game until Boxing Day of that year.
The Italian had a glowing reputation but constant injuries and loan spells away from Anfield with Juventus and AC Milan meant that he only managed to make 28 appearances in total before being sold to Fiorentina.
For the fee alone, the signing of Aquilani has to be considered one of the worst in the Premier League era by the club.
6 Pegguy Arphexad
Gerard Houllier signed his compatriot from Leicester City after the goalkeeper produced a fine display against Liverpool in the F.A. Cup in 2000. Although the goalkeeper arrived on a free transfer, it was a strange signing as he hardly played a game for the club.
He only managed to make a total of six appearances for Liverpool before loan spells away and a permanent transfer to Coventry City in 2003.
The Frenchman's name was once again brought to the limelight a few weeks ago when Jamie Carragher summed up his disappointment that Gary Neville was leaving Sky Sports for Valencia with a tweet that quipped ' Gutted! This reminds me of when Pegguy Arphexad left for Coventry.'
5 Robbie Keane
Irishman Robbie Keane joined the Anfield club in the summer of 2008 in a £16.8 million deal from Tottenham. Rafa Benítez had intended Keane to be the final piece in a title-winning jigsaw but things didn't exactly go according to plan.
Keane became a misfit at the club and was re-sold to Tottenham for a much reduced price of £11.69 million just half a season later. It was a terrible piece of business for Liverpool.
Keane only played 28 games for the club with a return of seven goals before going on to have successful spells with Celtic and LA Galaxy.
4 Djimi Traore
Djimi Traore will fondly be remembered by Liverpool fans for scoring one of the best own-goals of all time in the 2005 FA Cup against Burnley.
The Malian was one of Gerard Houllier's signings from French football and played over 100 games for Liverpool in what was a successful period for the club. Although the defender tried hard, he often made mistakes and was considered a liability when playing.
After leaving Liverpool in 2006, Traore represented seven clubs before retiring from the game with Seattle Sounders at the end of the 2014 campaign.
3 El-Hadji Diouf
Striker El Hadji Diouf was welcomed to Anfield alongside Salif Diao after starring for Senegal at the Africans successful World Cup campaign in Japan and South Korea in 2002.
The £10.5 million fee that he commanded was a risk for the club but they believed that the striker had shown enough to become successful in English football. Diouf had made a promising start to his professional career in France and had a good scoring record with previous club Lens.
The player only managed to score six goals in 80 games before being off-loaded to Bolton Wanderers. Steven Gerrard commented that, "Diouf arrived with the most potential and he ended up causing the most aggravation." He was not wrong.
2 Mario Balotelli
Mario Balotelli was another Brendan Rodgers signing that didn't quite go to plan after Luis Suarez left for Barcelona. The Italian was a bizarre signing given that the manager had repeatedly stated that neither he nor the club were interested in signing the former Manchester City striker.
It turned out that that wasn't true and the petulant striker was signed for £14 million from AC Milan. Nothing seemed to go right for the striker at Anfield and he was the wrong sort of player to fit into the Rodgers philosophy.
Balotelli only managed four goals in 28 games before rejoining Milan on a season-long loan deal in August 2015.
1 Andy Carroll
The burly striker was signed by Kenny Dalglish for £28.7 million from Newcastle United in the January 2011 transfer window becoming the club's most expensive player in history. It was a blatant panic-buy in an attempt to replace Chelsea bound Fernando Torres who was sold.
Injury problems meant he didn’t make his debut until March and scored just two goals in his debut campaign. The following season he only managed nine in 47 appearances and was eventually sold by Brendan Rodgers to West Ham United for £12.25 million.
Injuries have restricted Carroll's playing time at West Ham, but the big striker looks to be finally fighting his way back to full-fitness after featuring regularly for the London club this season.
