Marouane Fellaini (Everton)
Estimated value: £24m
The powerful Belgian could perhaps act as a good replacement for Frank Lampard. Yes the Everton man is not exactly the same style of player as the England midfielder but like the Chelsea record goal-scorer the 25 year old provides goals from the centre of the park, supporting the strikers every chance he gets.
David Moyes leaving Goodison Park could well lead to interested parties looking to take advantage of any uncertainty and Fellaini has previously made it clear he wants Champions League football and a move to Chelsea may well be a distinct possibility.
