Arsenal’s midfield options have been dealt a significant blow after the full extent of Mikel Merino’s injury was inadvertently laid bare by his father, casting doubt over both his short-term availability and wider ambitions later in the year.
The 29-year-old picked up the problem during last month’s Premier League defeat to Manchester United, a game in which Merino scored but left the pitch with discomfort in his foot.
What began as a routine knock has quietly morphed into one of Arsenal’s most worrying injury stories of the season.
In a few words, Mikel Merino’s father has revealed a problem that is far more serious than initially anticipated, posing a potential threat to Mikel Arteta’s midfield plans.
What initially appeared to be a manageable issue has since proven far more complex, with surgery now required and no clear timeline for recovery.
A rare and uncertain injury
Speaking on the Spanish radio programme El Larguero, as relayed by football.london Merino’s father offered an unusually candid assessment of the injury, revealing it to be a stress fracture of a rare nature.
“It is a stress fracture. Something more internal. It is very rare. There is a bit of uncertainty about the timing, because there is no clear history of this type of injury,” he explained.
“Considering the problem he has, he is accepting the situation… you have to look on the bright side: there are injuries much worse than this one.”
Those comments underline why Arsenal’s medical staff are proceeding cautiously. Stress fractures in the foot can be notoriously unpredictable, particularly when surgery is involved, and recovery often depends on how the bone responds in the weeks following the procedure rather than any pre-set rehabilitation schedule.
Signed from Real Sociedad in the summer of 2024 for just over £30 million, Merino has become one of Mikel Arteta’s most tactically flexible options. While recruited primarily as a central midfielder, Arteta has repeatedly emphasised his intelligence, timing in the box and physical presence.
That adaptability was evident late last season when Merino was trialled as a No. 9, scoring twice against Leicester, and again this campaign as he has rotated between midfield and attack. His output reflects that versatility: seven league goals last season and four already this term.
Losing a player capable of filling multiple roles is particularly disruptive at a stage of the season where squad depth often defines outcomes across competitions.
Arteta’s cautious tone
Arteta has publicly acknowledged the unusual nature of the injury, echoing the uncertainty expressed by Merino’s family.
“It’s a very rare injury so we have to wait and see once we have the surgery, how that reacts daily,” the Arsenal boss said.
“I know Mikel is going to do absolutely everything that he possibly can to come back as quick as possible. But you have to respect the healing process.”
Those remarks hint at why Arsenal were tentatively linked with midfield reinforcements late in the January window, a reflection of how long the club privately expect Merino to be sidelined.

Beyond Arsenal’s immediate concerns, the timing is troubling for Merino at the international level. Spain begin their 2026 World Cup campaign in mid-June, leaving a narrow window for the midfielder to return to full fitness. His father suggested that national coach Luis de la Fuente is monitoring the situation closely.
“Coach Luis de la Fuente is someone who pays attention to every detail. He has surely spoken to Mikel and asked him how he is doing.”
Whether Merino features again this season remains unclear. What is evident, however, is that Arsenal are preparing for a prolonged absence – one that removes a uniquely valuable piece from Arteta’s tactical puzzle at a critical point in the campaign.
