Mourinho is saying that it's impossible to make a winning team in just one season....?

... by his words he is just building his team and to win everything right away is just impossible...... but didn't Pep Guardiola win EVERYTHING in his first season??? Oh I forgot he had the best players already when he came...hmmmmm.... correct me if I'm wrong but didn't Mouriho had C.Ronalda, Casillas, Higuain, Benzema, Xabi Alonso, Carvalho, S.Ramos, Ozil, Di Maria, Kaka, Lass, Khedira etc etc when he came???? I mean is not like he got Malaga's squad, he got the squad of the best players money can buy........ he got the squad of players that won 96 points in last season!!!! Don't you think that maybe just MAYBE the ''Special One'' is just a little bit overrated???
