#3 Cesc Fabregas
Widely considered to be one of the finest Spanish midfielders of his generation, it's fair to say that Cesc Fabregas has failed to light up Stamford Bridge this season.
Having been deployed alongside N'Golo Kanté in a deep-lying midfield role, it's clear to see that he prefers to play further forward in the number ten role - mainly as he's not mobile enough to patrol midfield in such a deep position of the park.
In his 24 league appearances this term, he's created four assists and a total of 56 goalscoring opportunities too. Cesc will turn 31 at the start of May and just like the aforementioned duo, will also enter the final year of his existing deal with the Blues too.
Long admired by Jose Mourinho, it's plausible to suggest that Manchester United may be interested in making a formal approach for the former Arsenal man in future. However, Cesc appears happy at Chelsea and will be keen to prove he can continue to provide quality for longer, making their decision to keep or sell him a more difficult one depending on whether they have a long-term midfield acquisition lined up.
