Jose Mourinho had to leave Real Madrid because he lost the dressing room, according to Raul Albiol.
The current Chelsea boss ended a tempestuous three-year spell in charge at the Bernabeu this summer - not before he'd allegedly fallen out with many of his leading stars.
In his last few months in charge Madrid relinquished their La Liga crown to rivals Barcelona, were knocked out of the Champions League by Borussia Dortmund and fell to rivals Atletico Madrid in the Copa del Ray.
Albiol, who has since joined former Chelsea coach Rafa Benitez at Napoli, says that Madrid's season started unravelling when Mourinho lost control of the dressing room in the final few months of the 2012/13 campaign.
"With Mourinho there was never a bad relationship, I always got along with him. That is normal with my boss," he told El Pais.
"The last three months at Madrid were unpleasant, because we lost the league, we were eliminated from the Champions League and lost the Copa del Rey Final.
"Maybe last year was the worst in respect of the dressing room atmosphere, but I will stick with the good and my relationship with Mourinho was normal."
Albiol says he is enjoying life in Naples under Benitez, who was in temporary charge at Stamford Bridge last season before Mourinho returned for a second spell in charge.
"I am back to enjoying the confidence of the coach, the tension of the games, it is what satisfies you as a professional," he explained.
"(Completing the move) took no time, in a few days we arranged everything. It was easy to decide - it was Benitez, they had already signed [Jose] Callejon, they had a project and Naples has always been a city for football.
"Benitez’s influence? I didn’t talk to the coach until I was taking the medical. But I have known him for years, in fact I made my debut at Valencia with him, in his final year, against AEK Solna in the UEFA Cup."
