5 Premier League summer signings that have failed to deliver

#1 Tiemoue Bakayoko

Without a doubt, Bakayoko has been the worst signing of the summer

The fact that Chelsea features twice in the list is a testament to just how poor their current season has been.

Brought in from Monaco for 36 million pounds, the Frenchman was considered as a long-term replacement for the outgoing Nemanja Matic. As it turned out, he isn't even a short-term replacement for the Serbian.

Life at the Bridge has so far been miserable for the defensive mid-fielders as everything he has touched at Chelsea has turned out to be catastrophic. A string of errors forced him out of the team, and when Conte showed him some trust, the Italian was rewarded with a red card in a crucial game.

Bakayoko's task is not to score goals but to defend the ball, and to turn defence into attack with intricate passing - and his passing is his biggest current weakness. He is nowhere near the player he was at Monaco and has been the biggest disappointment of the season.

To be fair, he is just 23 years of age, and with time and experience - combined with the physicality he exhibits, he could turn out to be a great asset to Chelsea. This season, however, he takes the cake for being the worst summer signing.
