Their team spirit was talked about as one of their biggest qualities.
It all ended in tears for the host nation last night as they were left stunned by a Germany side who raced into a 5-0 lead within the first half-hour of the game, booking their place in Sunday's final with a 7-1 victory.
It was always going to be a struggle for Brazil against one of the strongest sides left in the tournament given that they missed their talismanic figure in Neymar, and their captain Thiago Silva were absent through injury and suspension respectively.
In his video blog for Yahoo, Mourinho said: "A problem for them in my opinion was that the spirit they built in the national team - they probably thought that spirit would be enough, it would be their main quality to win the World Cup. It was not enough, it was enough to arrive in the semi-finals.
"In the semi-finals they faced a team that was better than them in that they behave with a fantastic stability and confidence in this game. Everything went in their direction, they catch Brazil in a defensive situation that's very, very, fragile."
Now Brazil have the difficult task of trying to bounce back from their humiliation at the hands of the Germans when they participate in the third place play-off in Brasilia on Saturday against the loser of tonight's semi-final between Argentina and the Netherlands, as they will look to salvage some pride from a World Cup when they were expected by their country to become world champions for a sixth time.
