nop Mourinho gave them character to beat barca instead of bending over and got them to finally get over minnows like lyon and reach consecutive semi-finals.
Ancellotti gave the final push
Ancelloti is a smart man, I used to think he is overrated. He saw that with a team like RM you can't play defensive football, it's a sin to have C.Ronaldo, Bale, Di Maria ( back then) and to play defensive football. Plus RM's central defenders are shit.
Mourinho's RM would never be so offensive.
There was a bigger chance of seeing Conte play 4-3-3 whole season than RM's playing offensive football.
