Fans convinced Onana was off his line after heroic penalty save sealed Utd's win

Fans are convinced that Andre Onana was off his line after the 27-year-old saved a last-minute penalty in Manchester United's win over Copenhagen.

The Cameroon international has struggled for form since his move from Ajax in the summer, but made himself a hero at Old Trafford last night.

Erik ten Hag's side secured their first Champions League win of the season, with Harry Maguire netting the only goal of the game.

Onana was called into action late on and saved a last-gasp penalty save after Scott McTominay committed a foul in the box deep into added time.

Several fans have since taken to social media, claiming that the goalkeeper stepped off his line and that Jordan Larsson should have been allowed to retake his kick.

One fan took to X, formerly known as Twitter, saying: 'Onana is 100% off his line when the ball is struck.

'Remember this next time the pitchforks are out at Old Trafford.'

While another fan posted: 'Guarantee Onana was off his line. Why are they not showing the replay?

'Onana was clear off his line, that penalty certainly should've been retaken,' another posted.

After the game, the Cameroonian made a promise to Manchester United fans following his heroic goalkeeping display against Copenhagen.

Onana told TNT Sports: 'Of course [there's resilience]. We are Manchester United, we're a very big club with big players.

'So it's just a matter of time, now we have to continue like this and we'll get through this.

'I just had to do my job, you know,' added Onana. 'I had to do it for us to win, to win against a very tough opponent, we had a great game.

'Great goal from the big man, Harry, and I'm very happy, we have to continue like that.'

Despite Onana's heroics in-between the sticks, fans remain convinced that he was off his
