RE: Is Romelu Lukaku leaving Manchester United soon?

Yeah..., you are right on that one. He is not a spring chicken anymore but he sure has his strength that will play well for Man U should keep him. There is more to what he can offer with his age which is experience with opponents and how to grind without fear.
Rashford is still upcoming and may have some fear with some tough opponents IMO, but then he can still grow bigger and better.
