He was never going to sign for Madrid because his heart was set on playing for Barcelona.
I think his wife has her immediate family living in Barcelona also so it was never really in doubt.
If he signed for Arsenal it would have only been the club which he left to join them instead.
If you think about it, we just stalled the deal they were cooking up anyway. Buy Suarez, sell to Barca for Sanchez plus cash.
They just did the transaction a different way around. Thing was, we were the ones who made the major profit not Arsenal.
