One Real Madrid star has revealed how Jose Mourinho made him angry when the current Chelsea boss was in charge at the Santiago Bernabeu, but that it was exactly what he needed and he was grateful for the source of fury.
Karim Benzema was talking to Al Jazeera, relayed by the Daily Express, ahead of his side's Champions League last 16 second leg against Schalke when he described some of the problems he has had since joining Real Madrid from Lyon for £25million in 2009, and how Mourinho helped him.
The France international has been the target of the Bernabeu crowd's anger on a number of occasions, not least in his first season there when he could only manage to find the net on only two occasions and was being labelled a waste of money.

Current Manchester City manager Manuel Pellegrini was in charge initially when he arrived, but the Chilean was replaced by Mourinho, and Benzema credits the Stamford Bridge boss with the turnaround in his form - his secret? Getting him angry.
"I have had criticism ever since I signed for Real Madrid. I really think it is something that has happened since I came to Real where I cannot make a bad pass or have a bad game," he said.
"At the start, it hurt me, but I am used to it now. It affects my family more. I knew that I was being criticised, that Mourinho criticised me, but it was his way of making me react. Actually, after that, I became mad. I worked as much as I could. Now, I come in before everyone else, I have treatment, I go to the gym, and I am the last to leave after training."
Mourinho's influence made Benzema one of the most feared strikers in Europe and last season he helped form the formidable combination of himself with Cristiano Ronaldo and Gareth Bale, nicknamed the BBC.
Jose the Great
If any further evidence were needed, this story by Benzema shows that the Blues boss is one of the greatest manager's ever and few can come close to him in terms of tactics and motivation of players.
We can see it now at Chelsea, Mourinho has curated a very tight-knit group with an atmosphere of camaraderie that is helping them get through the more difficult moments this season and they look as thought they are on course to win the Premier League.
