Arsenal Pre-Season Opener Against Girona: Arteta's First Test

Mikel Arteta stands on the brink of his first real look at Arsenal’s new summer shape, and it should begin with a debut.

Arsenal’s meeting with Girona marks their first official pre-season outing in front of supporters, a step up from the controlled, quiet run-out against MK Dons behind closed doors on Saturday. This one has a different feel. Noise, scrutiny, first impressions. The kind of afternoon where a manager learns a little more about who is ready and who is still playing catch-up.

Several big names are nowhere near ready. Those who went deep into the World Cup with Spain and England remain on holiday, their summers extended by the demands of a long tournament. William Saliba is sidelined for an “extended period” with a back injury, a significant early headache at the heart of defence. Martin Odegaard, fresh from a quarter-final run with Norway, has also yet to report back for pre-season and will not feature.

Into that gap steps opportunity.

Kai Havertz has been working alone at Bayer Leverkusen’s facilities, sharpening fitness away from the group, and is now in a position to walk straight into Arteta’s side against Girona. It would be a bold call, but this is precisely the moment to make it: low stakes on the scoreboard, high value in information. Arteta needs to see how quickly Havertz can mesh with the patterns and intensity that define this Arsenal team.

The squad is still knitting itself together. Gabriel and Gabriel Martinelli are due to link up with the group ahead of the match, but expectations around their involvement remain modest. Limited training usually means limited minutes, if any at all. Their real work will start in the coming days, not in a frantic early cameo.

At right-back, there is a more encouraging story. Ben White is edging towards his first action since a knee injury cut short his season. He sat out the MK Dons friendly but has been back on the training pitch for the last couple of weeks, steadily building towards match sharpness. Girona could mark his first steps back into competitive rhythm, a small but important checkpoint in Arsenal’s summer.

Not everyone is that close. Jurrien Timber still needs more time after minor groin surgery over the summer, his return carefully managed rather than rushed. Arsenal know too well the cost of impatience with key defenders.

With Saliba out and Timber not yet ready, the door opens for those on the fringes and those just arriving at the threshold of senior football. Max Dowman and Ethan Nwaneri will both be eager for minutes, the kind that can change a manager’s mind about loan plans or squad roles in a single sharp performance.

Cristhian Mosquera, meanwhile, stands at the centre of one of the day’s most intriguing subplots. He is set for another chance to show he can step into Saliba’s shoes at centre-back, at least in the short term. It is a demanding audition: read the game, hold the line, look comfortable on the ball, and convince everyone watching that Arsenal’s defensive structure can survive without its cornerstone.

Pre-season rarely delivers definitive answers. But it does reveal direction. For Arteta, Girona is not just about fitness and minutes; it is about glimpses. Havertz bedding in, White returning, Mosquera staking a claim, the kids pushing for relevance.

By the final whistle, Arsenal’s manager should know a little more about who he can trust when the real season starts—and who still has ground to make up.
