In a stunning revelation that’s sure to excite Arsenal fans amid a mounting injury crisis, Mikel Arteta may have a secret weapon hiding in plain sight. With the Gunners’ defensive line decimated by knocks and strains during this grueling 2025-26 season, the Spanish manager could turn to versatile midfielder Mikel Merino as an emergency centre-back. The £32million summer signing from Real Sociedad in 2024 has already proven his adaptability, and his past experience in defense could be the key to solving Arsenal’s backline puzzle.
Arsenal’s injury woes have deepened in recent weeks, particularly in the heart of defense. Key centre-back Gabriel Magalhães is sidelined with a hamstring injury until late December 2025, while William Saliba is dealing with a knock. Ben White and others have also been listed on the injury report, leaving the team short on options as the festive fixture pile-up intensifies. Kai Havertz, another versatile player, has been out with a knee issue since early in the season, further straining resources. Arteta has voiced concerns about player fatigue and the need for more rest, highlighting the absences of stars like Martin Ødegaard and Viktor Gyökeres
Enter Mikel Merino, the 29-year-old Spaniard who’s quickly become a fan favorite at the Emirates for his ‘jack-of-all-trades’ mentality. While primarily a midfielder, Merino has a hidden history at centre-back that could prove invaluable. During his lone season at Borussia Dortmund in 2016/17, he featured eight times in the Bundesliga, stepping into the heart of defense on three occasions. His first outing came in October 2016, where he helped Dortmund salvage a draw against Hertha Berlin after coming on late. A couple of months later, he played on the right of a back-three in another comeback draw against Augsburg. His final defensive appearance for Dortmund was in March 2017.
Merino’s defensive credentials extend beyond club football. He was a regular for Spain’s Under-21 side, slotting into the backline three times during that period. Though he hasn’t played the position regularly since, his willingness to adapt shines through. In a revealing interview with The Guardian earlier this year, Merino shared his eclectic positional history: “I’ve been a left-sided centre-back. At Dortmund I played there in a three. And in a back four, in the Spain Under-21s. I’ve played as a number six… I’ve played as a number eight… I’ve played as a number 10… as a kid, I played here, on the right wing…” He even joked about starting out as a goalkeeper in school but quipped, “No more: I have to protect my shoulder now.”
When pressed on his favorite role, Merino pointed toward the edge of the box and said, “Pfff, I don’t know. Lately, I like this one. You know, I’m getting a taste for it.” This season, that taste has seen him thrive in multiple positions, including as a centre-forward. Merino has already racked up impressive numbers, with 3 goals and 3 assists in 13 Premier League appearances for Arsenal in the 2025-26 campaign.
His latest heroics came in Arsenal’s 2-0 victory over Brentford at the Emirates on Wednesday night, where he led the frontline, breaking the deadlock in the opening 15 minutes with a smart header past Caoimhin Kelleher before assisting Bukayo Saka in stoppage time.
Arteta couldn’t hide his delight post-match, grinning as he told Sky Sports: “He was immense again today. The way he scored the goal, super smart. His timing, the way he wins the position and execution. He makes the team much better.”
As Arsenal brace for a hectic festive period, Merino’s versatility could be the wildcard Arteta needs to keep their title challenge alive. If the injury list grows any longer, don’t be surprised to see the £32m star dropping back into defense—proving once again why he’s the ultimate utility player in red and white.
