Consistently? He was only there 3 years. They won the league twice, the 3rd of those years ManYoo won it again and Mourinho got sacked.
As for Real, they finished 3 points off Barca with 96 points (the 3rd placed team got 71 points) the season before he got there. He's hardly transformed them from also-rans to champions, they were already very close to Barca before he got there.
