It's Iker Casillas's birthday today, and he's got just what he wanted. Real Madrid have confirmed that Jose Mourinho will leave the Spanish club at the end of the season, something that basically everyone knew was going to happen anyway, but it's official now. So is he coming back to Chelsea? We assume so, but how will it go? Will the squad be suited to his style? Is it a good idea to come back? Do the rest of us want him...?
