It has entered a spiral, opponents feel that they can do it and they do. It’s like little children, who go as far as you allow them to go. It’s a deal I don’t like. They kicked him. That is an aggression, it was an expulsion,” Mourinho added, about an incident in Saturday’s 2-1 win at Espanyol when the Brazilian was kicked in the back by the home team’s scorer Cala."Except for a few things, I really liked the refereeing. I understand that as for a red card for the kick to Vinicius, the referee hasn’t seen it. I understand that the fourth official did not want to, and I can say that VAR did not do its job very well. “But I trust the Spanish refereeing. I always trust it, in the Champions League too. I don’t think something like 'he’s a friend of Negreira’, no. They have had decisions that have influenced results, but it happens,” Mourinho said, in a veiled dig at FC Barcelona.MORE FOR YOUMourinho doesn’t want to be idolised by Real Madrid fans on his return to their homeWednesday’s match against La Real will of course be a first in the Spanish capital since Mourinho originally left the club more than a decade ago in 2013.Mourinho doesn’t want any special treatment, however, just because of his name or social norms."I don’t want the Bernabeu to receive me in a particular way. I want it to welcome the team as its passion. At one point that love was going through a complicated phase last season. Now we are not starting from scratch. “I’m not important,” Mourinho insisted. "I’m able to control my emotions and play normally in a game that is not normal because it’s a three-point game. I would like the team to feel something different from what it has felt last season."Real Madrid vs. Real Sociedad will kick off at 21:00 local time on Wednesday evening in Spain.
