Speaking to reporters, the English manager said: "I never make those guarantees about any player and it’s not to do with Alex’s future but I’d be foolish to sit here and do anything like that. We want to keep our strongest players, I’ve said that ever since I’ve been here and sat in this seat.
"We have to try and keep our best players and bring in more good players to make us even stronger because the ambition of the club and everyone connected with the club is long-term success and that’s the only way to get that."
