#1 Romelu Lukaku
This is an interesting one. Romelu Lukaku started life at Old Trafford with 27 goals last season across all competitions - carrying on his fine form from Everton where he had scored 20 goals or more in each of the previous 3 seasons.
But his performance began deteriorating towards the end of last season and things have begun to unravel rapidly this season. Mourinho is well known for his third season syndrome and Lukaku might just have been caught in the crossfire.
He has only four league goals to his name this season and was dropped from the starting eleven by Mourinho for their last match against Everton. The whims and fancies of Jose Mourinho are well known.
It was the Portuguese who sold Lukaku to the Toffees from Chelsea. They are known to not have a great relationship despite Mourinho making the Belgian his marquee signing last summer.
Lukaku's return to Chelsea would be a fairytale one. The Blues were the first big club to make a note of his immense talent when they signed him from Anderlecht in 2011. He never really got a chance at Stamford Bridge but this might just be his chance to prove a point.
