With the transfer conditions not very good, I won't be angry with Anceloti if I become Perez. Two trophies shouldn't be too bad for Madrid this season. So giving the option of one year and freedom of shopping certainly provides another good opportunity for him. Maybe after that Perez has the right to decide Anceloti's career henceforth. Anceloti this season does not have ideal players. The hectic schedule of old players, that is their main factor at the moment.
Doesn't Ancelotti have the right to be blamed for his statements in the past when he said he didn't need new players this season? I think Ancelotti is too sure and confident in the players he has while some unforeseen things like player injuries have brought his level down. Real Madrid's aggressiveness is not as good as last season, that is because some of the players available are not as good as expected.
I don't know how Ancelotti's future will be at Real Madrid right now after failing to win La Liga and also the Champions League. Real Madrid may need to respect that, but this team tends to expect the coach to present the title at the end of the season instead of just talking about the title last season.
