The Fernch international midfielder joined the 'Blues' in a £40 million move from Monaco, and arrived with a big reputation after having helped his side win the French league against titans PSG.
While he managed to start on 25 occasions for the club in the last campaign, he failed to put in consistent performances for the club and left fans frustrated given the fee that had been paid for his services.
Bakayoko failed to get in to the French squad for the World Cup in Russia as a result of his poor form, and with the arrival of Italian international midfielder Jorginho at Stamford Bridge it seems that he will not start regularly in the league this season.
His place in the team was put under even more threat after strong rumours that Matteo Kovacic would be joining Chelsea from Real Madrid on loan.
Despite playing in the pre-season win over Lyon on Tuesday night, 'Sky Sport' claim that he is close to singing for Milan on loan next season.
