Why would we not want Rafa?
People will quickly question whether a manager has won anything. In the same breath, people will quickly discount everything that Rafa has won: two league titles in Spain; a Champ League title; and a UEFA Cup. He had a dire final season in England, but that was on the heels of a second-place finish and in the midst of a crisis in ownership. Common knowledge says that he stinks in the transfer market, but the evidence says otherwise: he made some clever signings while at Liverpool and even turned a profit there in the transfer market.
He should be the man.
