Arsenal Women have lost the one player they could least afford to. Mariona Caldentey, the reigning WSL Player of the Year and the creative hub of Renee Slegers' side, faces eight to ten weeks out with a significant hamstring injury — and she leaves behind a team already stuck 10th in the table, winless in four league games and running out of time to save its season.
Eight to ten weeks on the sidelines
Caldentey was injured during Arsenal's 4-2 WSL defeat away to Manchester City on October 4, coming off around half-time, and she subsequently withdrew from international duty with Spain. Slegers gave the full update on Thursday, as FAWSL Full-Time reported: "It's a bigger hamstring injury, and the estimation right now is between 8 to 10 weeks. We're re-scanning and we did a re-scan this week and the healing process looks good. Of course we're hoping for less, but it's a bigger hamstring injury."
Counting from the original injury, that timeline points to a return somewhere between late November and mid-December — in other words, Caldentey misses this entire block of fixtures. And she is not the only absentee. Summer signing Selina Cerci has had surgery on her knee, Chloe Kelly is out with a hamstring issue, and Daphne van Domselaar, Michelle Agyemang and Katie Reid are all sidelined with knee injuries. Arsenal's treatment room is as crowded as their fixture list.
Why there is no like-for-like replacement
Some players can be rotated. Caldentey cannot. The Spain international, who joined from Barcelona in 2024 and was voted the WSL's best player last season, is the midfielder who receives the ball between the lines, sets the tempo and threads the passes that turn Arsenal's possession into chances for Alessia Russo and Caitlin Foord. Slegers said it herself this week: "We're gutted to lose Mariona. She's been so good for us for a long time. Our midfield unit is important for us — it's the spine of the team and connects everything on the pitch, both when we attack and defend."
The timing could hardly be worse. Arsenal have scored just four league goals all season — only bottom club Charlton have fewer — and their creativity was already under scrutiny before they lost their chief creator. Remove Caldentey and you do not just lose a player; you lose the mechanism that makes the whole attack function.
So who fills the gap?
Slegers has promised solutions rather than excuses: "We'll have to find the right solutions, play the players to their strengths, find the right balance in the middle of the pitch." She pointed to Kyra Cooney-Cross, now back available, and to Georgia Stanway as reasons for optimism, and Arsenal are not short of midfield names — Frida Maanum can play as the number ten, captain Kim Little brings control and experience, and Cooney-Cross offers progression from deep.
The problem is that none of them is Caldentey. Maanum is a goal threat who plays on the last line more than between the lines; Stanway and Cooney-Cross build play from deeper positions; Little is at her best keeping the game moving rather than unlocking a set defence. The likelihood is that Slegers rebuilds the role by committee — more creation shared between the midfield and the wide players, with Olivia Smith, now pain-free after scoring twice for Canada during the break, asked to carry a bigger attacking load. It can work, but it changes what Arsenal are.
So what happens next?
The run that decides Arsenal's season starts today. Birmingham City at the Emirates is, as Arseblog News put it, step one of the recovery — a home game against a winless side that Arsenal simply have to win. After that come Spurs and Liverpool in the league and a Champions League trip to face Barcelona, Caldentey's old club, in a fixture she will now watch from the stands.
Arsenal sit 10th with five points, already 10 points behind leaders Manchester City, and Slegers has already conceded her side are not in the title conversation. The realistic fight now is for a Champions League place — and a bad month without their best player could put even that beyond reach. The club backed Slegers during the international break, but backing is not the same as patience, and it will be results, starting this weekend, that decide how long it lasts.
Beyond the Final Whistle: Losing Caldentey does not end Arsenal's season, but it removes their margin for error. Slegers has the squad depth to survive this block; what she no longer has is the one player who could win a tight game on her own. If Arsenal are still in the Champions League race when Caldentey returns in December, this injury will be a footnote. If they are not, it will be remembered as the moment the season slipped away. Can Arsenal cope without her? Let us know in the comments.
