Lukaku has to do a lot to show he's better then higuain who has consistently scored around 30 goals for 4 years in a row now, not to mention being better on the ball. And it has nothing to do with money. But also not really the point. Sure if Lukaku went to Juve, he'd score goals as he would anywhere. But again, he wouldn't lift them up to that top level would he?
Barca/Bayern/Madrid wouldn't sign him as they are able to get the very best... isn't that what I'm saying? They are the top teams and if we want to get there, Lukaku isn't going to be the player to take us there. Not everyone can get there, but I'd like to think at Manchester United with the money we have, we should strive to get there. Basically if I'm thinking long term and in a hypothetical best case scenario where we are among Europe's elite a few years from now, on par with Barca/Madrid, I'd definitely think it's more likely we got there through Martial developing into a world class striker rather then Lukaku still being there. And I really like Lukaku and think he'll do well for us... It's just we'll always have that limit to how good we can be with him as the striker, because the striker really is the focal point of attacks.
