I was chatting to a Chelsea fan the other night, who was actually really sound and level headed. He was quite complimentary of Everton and we got chatting about Lukaku. I said to him that after watching him for half a season, I can see why Mourinho decided to loan him out, as he still has some improving to do. He agreed with me and was surprised that someone else shared the same viewpoint, as all of his other Chelsea mates think Mourinho is an idiot for loaning him out.
The way I see it, Lukaku is best here for his own sake, but Chelsea could have no doubt made good use of him. In the long run it's probably better for Lukaku to have this extra year of an almost guaranteed starting role at a team with lower expectations, whether he stays at Chelsea or not.
