Exactly this.
In a contact sport like this....his career can end at any time.
AS is playing his cards right. He will be set for life when he signs that contract. He will be playing in the top league with the big boys. If he proves that he can do it at that level...consistantly, they will then be banging on Bournmouth's door...and he will be off again.
Who on here would honestly refuse that chance?
Fair play to him, I wish him well.
