Lukaku says he moves to Everton for regular first team football.
"I was sitting in my hotel room in Brussels when the phone went to tell me I was going out on loan again," he said, ahead of Belgium's World Cup qualifier with Scotland. "It was 7 pm, and that was the first I knew of it. There had not been a mention of it before then, but after speaking to my parents, I decided to take the plunge.
"I talked to the manager as well, and while what he said was confidential, it just underlined that he is the best coach I have worked with. Some beat about the bush, but he comes out straight and tells you what he thinks. As a player, that is what you want.
"The important thing, at 20, is to be playing, and while West Brom was an option, Everton was a better one. There are a few things I need to improve in my game, and Everton's footballing approach and possession play can be perfect for me.
"My movement and runs to the far post and near post could be better, and I have already had a good, long conversation with the manager Roberto Martinez about that. I've also known Kevin Mirallas since I was 14, and that should help. We talked about it (the loan move) all last night."
