Manchester United’s 2025/26 season hit a new low after their humiliating Carabao Cup exit to League Two side Grimsby Town on Wednesday night.

The Red Devils fell two goals behind inside the first half hour following errors from goalkeeper Andre Onana.

Though Bryan Mbeumo and Harry Maguire managed to drag the game to penalties, Manchester United could not make the shootout count, with Grimsby sealing one of the most remarkable results in recent tournament history.

According to Sky Sports, the defeat adds to the pressure already mounting on head coach Ruben Amorim, whose side finished 15th in the Premier League last season and are still winless in their opening three matches of the new campaign.

For many, this latest setback for the Red Devils is another sign that the Portuguese manager’s project is already failing.

Former West Ham and Crystal Palace defender James Tomkins has suggested that if Manchester United decide to part ways with Amorim, they should turn their attention to Oliver Glasner, GOAL reports.

The Austrian coach, who currently manages Crystal Palace, has earned praise for transforming the Eagles into a more competitive and organised side in recent seasons.

Speaking in a recent interview as captured by, Tomkins stated: “If the Man Utd job comes up I think Oliver Glasner is definitely a name that will be mentioned, and I believe he was linked to Bayern before.

“It will be interesting to see how that unfolds, because he’s certainly going to be linked with the bigger teams.” Glasner, who previously led Eintracht Frankfurt to win the Europa League, has already proven his credentials on both domestic and European stages.

Last season, he led Crystal Palace to win their first-ever trophy after winning the FA Cup, and also won the Community Shield at the start of the 2025/26 season.

Despite the shock defeat, sources close to Manchester United insist that the board remains committed to Ruben Amorim.

The club hierarchy reportedly views his project as a long-term process rather than one to be judged by short-term setbacks.

Man United’s owners are keen to avoid a cycle of managerial sackings that has troubled the club since Sir Alex Ferguson’s retirement.

This summer, Amorim was heavily backed in the transfer market, with over £200m spent on attacking reinforcements.

Another poor run of results could force the Red Devils’ hand, and pressure from fans and media alike may eventually become too loud to ignore.

🚨 𝗕𝗥𝗘𝗔𝗞𝗜𝗡𝗚: The Manchester United dressing room are now questioning Ruben Amorim's 3-4-3 tactics and man-management style.

There's a feeling from within the squad that he might resign next week.
