José Mourinho's Preseason Challenge at Real Madrid: Key Players Under Pressure

The José Mourinho era at Real Madrid has begun not with fireworks at the Bernabéu, but with running drills under a hot July sun at Valdebebas. Preseason is underway, the squad is thin, and the message is already clear: reputations won’t save anyone.

With a raft of World Cup returnees still on the beach and Éder Militão in the treatment room, Mourinho is working with a stripped-back group in his first week. Those who weren’t in Qatar reported on July 13. The rest will drip-feed back in over the coming weeks, walking into a very different Madrid than the one that finished another trophyless season.

The club has handed Mourinho a new-look staff, including former midfielder Sami Khedira, and a blunt mandate: restore a winning mentality after two flat years. For some players, that means the summer is not a tune-up. It’s an audition.

Six Madrid Players for Whom This Preseason is Absolutely Unforgiving

Trent Alexander-Arnold: No Hiding Place at Right-Back

Trent Alexander-Arnold arrived early. Not because he wanted to, but because he had to.

Thomas Tuchel left him out of England’s World Cup squad, a decision that stung. While others were chasing a trophy, the former Liverpool full-back was among the first to report back to Valdebebas, thrown straight into Mourinho’s notoriously demanding fitness work.

His first season in Madrid wasn’t a disaster. It wasn’t a triumph either. The same questions that followed him out of Anfield still hang in the air: can he defend well enough, often enough, to justify everything he offers on the ball?

Now there’s Denzel Dumfries breathing down his neck. Mourinho has rarely shown patience with defenders who switch off or freelance out of position. Alexander-Arnold’s range of passing and creativity from deep could be priceless in a 4-2-3-1, but only if he convinces his new manager he won’t be a permanent emergency on the flank.

This summer, every defensive duel, every recovery run, every tactical drill counts. Under Mourinho, full-backs either toe the line or step aside.

Dean Huijsen: Talent on the Clock

Dean Huijsen could easily have been packing for a World Cup final with Spain. Instead, he’s chasing a starting spot in a back line about to be ripped up and rebuilt.

Luis de la Fuente’s decision to take Atlético Madrid’s Marc Pubill over Huijsen for the tournament cut deep. The young center-back had played a meaningful role in qualifying, only to watch the main event from home.

His first full campaign in Madrid colours mirrored the team: bright spells, then shaky moments in the crunch. The raw material is obvious. Size, calm on the ball, and a defender’s instinct that can’t be taught. But Mourinho is already reshaping the defence, with Ibrahima Konaté, Marc Cucurella and Dumfries arriving and at least one more reinforcement expected.

History says Mourinho trusts experience at the back. He prefers scars to promise. Yet with Konaté still on World Cup duty and Militão sidelined, Huijsen has a rare window: the early preseason games are his stage.

If he looks commanding and secure, he can force his way into Mourinho’s plans. If he wobbles, he may find himself nudged to the margins just as the serious business begins.

Eduardo Camavinga: At a Crossroads

Eduardo Camavinga is back early too, and not by choice. Left out of France’s World Cup squad, he returns to Madrid with his future hanging in the balance.

A couple of years ago, he looked like one of the pillars of Madrid’s next midfield. Now, after a period of regression and inconsistency, he’s a question mark. Several Premier League clubs have been linked, but so far, no one has pushed hard enough to turn rumours into a concrete bid.

Camavinga is understood to want to stay. He believes he can fight for his place. The issue is simple: where does Mourinho see him? As a deep-lying midfielder in a double pivot? A high-energy presser? A rotation piece?

With the World Cup contingent absent, he has a rare chance to show Mourinho, day after day, what he can bring. The Frenchman’s blend of ball-winning and progressive carrying should appeal to a coach who values structure but loves transitions.

If he can’t impose himself now, with the training ground quiet and the competition still on holiday, it’s hard to see when he will.

Brahim Díaz: From Bit-Part to Leading Man?

For Morocco, Brahim Díaz is a star. He was one of the standout figures in their run to the World Cup quarterfinals, taking on responsibility, demanding the ball, and playing with the swagger of a man who knows he’s central to the plan.

At Real Madrid, he’s still a supporting actor.

At 26, Díaz is no longer a prospect. He’s at the age where a player either nails down a starting role or becomes a permanent squad option. The opportunity is there: Rodrygo Goes is still recovering from an ACL injury, and Mourinho’s preferred 4-2-3-1 needs a reliable, dangerous right-sided attacker.

Díaz has shown flashes in white, but not yet the sustained influence he enjoys with his national team. His ability to drift inside, link play and threaten goal from the half-spaces could make him a natural fit in Mourinho’s system.

For now, he’s resting after Morocco’s elimination on July 9. When he walks back into Valdebebas, he does so knowing this preseason could define his Madrid career. Either he convinces Mourinho he can carry the right wing, or he risks being filed away as useful depth and little more.

Arda Güler: Genius in Search of a Role

Arda Güler’s World Cup ended early with Türkiye’s group-stage exit, so he’s expected back at Valdebebas sooner than most. For his country, he’s indispensable. For Madrid, his place is far less certain.

The 21-year-old’s talent is undeniable. He sees passes others don’t, glides between lines, and carries the kind of creative spark that usually gets protected, not pressed. But Mourinho’s teams are built on work rate, discipline, and physical resilience. Where does Güler fit in that blueprint?

The double pivot in a 4-2-3-1 demands strength, tactical intelligence, and constant defensive work. Does he have the engine for that? Out wide, he’d be asked to track runners, press full-backs, and still produce in the final third. The No.10 role, the most natural home for his gifts, appears locked down by Jude Bellingham.

On top of that, Bernardo Silva’s arrival adds another layer of competition in the creative zones, and he is exactly the sort of all-round, tactically obedient player Mourinho gravitates towards.

One report from SPORT suggests Mourinho phoned Güler after Türkiye’s exit, offering reassurance and backing. Words are one thing. Training ground choices are another. The young Turk now has to prove he can marry his artistry with the intensity and discipline his new coach demands.

Endrick: Hype, Doubt, and a Defining Summer

Few players polarise opinion quite like Endrick. For some, he’s a generational forward. For others, he’s a meme wrapped in a highlight reel.

His numbers at Lyon last season were no joke: 16 goal involvements in 24 matches, strong enough to earn him a place in Brazil’s World Cup squad. That should have been the springboard to a starring role at Real Madrid. Instead, Carlo Ancelotti largely looked elsewhere, and the debate around Endrick’s true level only grew louder.

He’s still only 19. That youth has sparked constant talk of another loan, another year of development somewhere else. Recent reports, though, suggest Madrid plan to keep him in the squad this season.

That decision only raises the stakes. Where does he fit alongside the established attacking options? Can he convince Mourinho he’s ready for meaningful minutes in a side under pressure to win now, not later?

Preseason will offer clues. Mourinho will study his movement, his work without the ball, his attitude in training. Endrick doesn’t need to settle the “generational talent or overhyped prospect” argument in July. He does need to make sure that, unlike under Ancelotti, his manager sees him as part of the solution.

Because at Madrid, especially under Mourinho, summers don’t just build fitness. They decide futures.
