Huge decision? Firstly, he's contracted to Spurs. Secondly, there's been no bid from any club and lastly, if he continues to play like he has been there won't be any bids.
I don't understand why everyone makes out like he's the messiah with the choice of any club in the world when he struggles with large parts of his role so often. If I were him I would be more worried that Madrid won't want someone that is so hot and cold.
There is this small time mentality here that we can’t do better
