#2 Tiemoue Bakayoko
Tiemoue Bakayoko, who was the subject of a £40m transfer from AS Monaco to Chelsea last summer, has not justified his price-tag up until this point and if the early signs from pre-season are anything to go by, then the Frenchman's nightmare in a Chelsea shirt looks set to continue.
The midfielder was unofficially voted as Chelsea's worst player from the 2017/18 campaign and it his career has only gone downhill ever since arriving in London.
At least some of the optimistic bunch among the Chelsea faithful would have hoped that the 23-year-old would recapture his form in a midfield three under Maurizio Sarri but it has not quite turned out that way for the player. Bakayoko disappointed with his passing during pre-season and was ridiculously out of position during many instances, failing to complement his teammates on the pitch.
The arrival of Mateo Kovacic is expected to bring down the curtains on his horror show in West London with AC Milan interested in signing the player on an initial season-long loan with an option to make it permanent.
