The following players were signed by Chelsea and had been expected to hit the ground running. Unfortunately, all failed to contribute much at all to the club and did not even show glimpses of good form over a sustained period of time, unlike other signings considered flops on the whole, such as Fernando Torres.
Danny Drinkwater
Drinkwater is probably the worst Chelsea signing in the modern era. His career peaked during the 2015/16 season when he helped Leicester City to win the Premier League title. Drinkwater moved to the Blues during the summer of 2017 for a fee of £35 million. He was quickly deemed surplus to requirements at Stamford Bridge and has made just 12 Premier League appearances for the club, which he is unlikely to add to. Drinkwater had an unsuccessful spell with Burnley in an attempt to revitalize his career and is currently on the books of Aston Villa on loan. He has yet to sparkle for the Villans, who are considered a safe option for relegation for those creating football accumulators.
Marko Marin
Marin caught the world’s attention during the 2010 World Cup as he delivered some promising displays for Germany in South Africa. Marin earned a move to Chelsea in 2012 from Werder Bremen and was dubbed as the next Arjen Robben. During his first season with the Blues, he made just six Premier League appearances for the club and it became evident that he was not a fit at Stamford Bridge. He then had four unsuccessful loans and his career never really took off. The 31-year-old is currently playing for Al Ahly in Saudi Arabia.
Gael Kakuta
The DR Congo international joined Chelsea as a teenager in a controversial transfer from Lens in 2007. Kakuta was impressive for the Blues reserve team and the club’s former midfielder Michael Ballack heralded him as a future star. Kakuta never quite progressed and had six unsuccessful loan spells during his time with the Blues. He has turned out to be a journeyman footballer.
