#2 Romelu Lukaku
It's time to admit that the experiment of signing Alvaro Morata back from Juventus has failed. Although it's only been six months, the Spaniard is yet to really impress anyone within the club let alone any of his critics.
Morata is still young and it's only because of that will Real Madrid be able to sell him on for a profit to interested clubs. But who could they sign to replace him? Romelu Lukaku would be the perfect signing.
The Belgian has been sensational ever since arriving on British shores – barring the first year at Chelsea where he failed to play much – and he's grown and grown to become one of the best young forwards in the game. Still only 23, he has the world within his grasp and could very well go on to become a legend should he continue his present trajectory.
