I can imagine some £60k a week wages but not for an unproven player.
Don't get me wrong, he could be a fantastic player who will shine away from Chelsea and playing first team football every week. Quite a gamble to take though.
Madness indeed. Amazingly Chelsea make a profit on the players they loan out so presumably whoever he goes to will be paying his wages and a loan fee. A hell of a lot of money for a player that I have never heard of!
