Jose Mourinho's Harshest Critic Shocks Everyone With Stunning Reversal—Is He Being Played?

Former Real Madrid captain and one-time rival of José Mourinho, Iker Casillas, has stated that the 63-year-old coach has come back to the Bernabéu as a "different" man.

Goalkeeper Casillas was a central figure in the squad during Mourinho's initial spell at Madrid from 2010 to 2013. The pair claimed both the Copa del Rey and La Liga titles together, but an apparent falling-out between them resulted in Casillas being dropped to the bench during the 2012–13 campaign as the relationship between Mourinho and the club deteriorated.

To this day, considerable speculation surrounds exactly what transpired between the two. In the recently released Netflix documentary series bearing his name, Mourinho implied that Casillas had become "spoiled," and expressed his disapproval of Real Madrid players maintaining close ties with their Barcelona rivals as the two clubs competed fiercely for silverware that season.

The fallout from the Casillas-Mourinho dispute took a serious toll on the dressing room, as Madrid finished the season without a trophy and the manager left under a dark cloud.

"With José Mourinho, it was a marriage that ended badly," Casillas told L'Equipe.

When Mourinho's name began to be linked with a stunning return to the Bernabéu earlier this year, Casillas posted on X: "I have no problem with Mourinho. He seems like a great professional to me. I don't want him at Real Madrid. I think other coaches would be better equipped to coach at the club of my life. Personal opinion. Nothing more."

Casillas was also rumored to be set for a return to Madrid in a senior executive role under unsuccessful presidential candidate Enrique Riquelme, who had opposed Mourinho's comeback.

'Different Idea'—Casillas More Hopeful on Mourinho

Casillas's most recent remarks about Mourinho, however, seem to indicate that his outlook has shifted considerably.

Speaking with former Atlético Madrid assistant coach Germán Burgos on his own YouTube channel, Casillas said he sees a "different" Mourinho compared to the one who previously managed Madrid.

"He's a different José. He doesn't look like... He looks like the same successful coach, with his talent and all, but he's come with a different idea," Casillas said.

"The one who has come to Madrid is a different Mourinho, he is the same successful and talented coach, but he has arrived in a different way."

The iconic goalkeeper refrained from revisiting past grievances, simply adding: "I still laugh about it, I remember a lot of things."

Casillas ultimately outlasted Mourinho at Madrid by two years, going on to claim the third Champions League title of his career in the season following the Portuguese manager's exit.

Warning Signs for Madrid

While Casillas is sounding more optimistic these days, there are indications that Madrid may be on the verge of repeating past mistakes.

When Mourinho returned to Madrid this summer, he introduced himself as "more mature now, less emotional, more controlled." Many supporters have been hopeful that one of football's most volatile personalities had shed his more disruptive habits from previous clubs and evolved into the steady hand Madrid requires to return to its best.

However, just one month into the 2026–27 season, there are already signs that the chaos long associated with Mourinho's career may not be far behind.

The 63-year-old arrived at his post-match press conference following the Madrid derby loss armed with printed documents to challenge the match officials and leaned into conspiracy theories targeting Los Blancos.

"If 'they' leave us in peace, and let us compete on an even playing field, there's a long way left," he told reporters, when asked whether his side could still challenge for the title despite sitting six points adrift heading into the first international break.

What has yet to occur is any significant breakdown in his relationships with his own players. Only time will tell whether Mourinho truly has changed.
