The former Manchester United defender is getting over a minor knock and hopes to face Real Betis: "I could play in central defence. I don't mind it, I've played there for Argentina.
"There's little difference between Real and Manchester United. The only thing that's surprised me is the sun! I am training under the sun every day and that's great!"
Heinze added: "English football is unlike anyother competition in the world. It's very different to Spain, but I am confident of adjusting very quickly."
"He has shown himself to be an excellent player," added Heinze. "I know there's a debate about when you should go out and when you shouldn't, but I don't believe he has done anything deliberate. He's a nice guy.
"I admit it's good for us that he's not playing, because surely he would help Barcelona pressure us more."
