4. Romelu Lukaku
The Chelsea striker may head out of London with Diego Costa coming to Stamford Bridge. And he is the main striker in the Belgium ranks with Benteke injured. This means he has even more chance to succeed at the World Cup and Chelsea having more chance of getting a hefty transfer fee for the youngster. Atletico Madrid may be the place where Lukaku will end up going, but not without a substantial fee if he shines at the Cup.
