5 players Chelsea should have kept

#4 Romelu Lukaku

Lukaku during his time at Chelsea

With over 80 goals in the Premier League and the highest goal scorer for Belgium at just 24 years of age, Romelu Lukaku is a goal scoring machine. Strong, powerful and good in the air, Lukaku is the classical centre-forward who likes to play with his back towards the goal, holding up the ball and bringing his teammates into play.

After the departure of Didier Drogba, Chelsea have never been able to replace him. Diego Costa's goalscoring prowess offered a ray of hope, but that too flickered out after a couple of good seasons. The gravity of Chelsea's mistake was understood when the £75m striker snubbed a return to the Blues in favour of Old Trafford where he has done reasonably well.

Morata has been in tremendous form this season no doubt but Lukaku remains one of Chelsea's biggest transfer fails.
