This. I said in the Lukaku thread that i dont think Mourinho sees him as the main man for another 3 to possibly 4 years, due to his all round game. He's got the talent, the stature, he will build that strength and his touch will get better but Chelsea wont put him in for years and would rather go out and buy a tried and tested striker!.
I think Chelsea want 2 from Rooney, Falcao, Jackson Martinez & Diego Costa and all them are more proven and ready than Lukaku and would lead Chelsea's attack for a fair few years, so where will this leave Lukaku?. Chelsea will no doubt want to keep loaning him out, so he improves, gets better and gets the necessary experience. But Lukaku wont stand for that i wont of thought, he might do for another year possibly, but no more than that, but i dont think he'd dislodge any of them if they were at Chelsea for next 3 or 4 years!.
So for me, IF Chelsea make big signings up top, i think them and Lukaku have a decision to make?!.
