Hubert Graczyk helped Manchester United prepare for matches against Arsenal and Southampton.

The young goalkeeper hasn't been officially named in a matchday squad, but he's been briefly promoted to the first-team set up to help United prepare for their last two matches.

Graczyk was spotted warming up with Andre Onana and Altay Bayindir before United faced Arsenal in the FA Cup third round. He was put through his paces, facing shots from his teammates, and was present again before Thursday's match again Southampton in the Premier League.

The signing of Graczyk on a free transfer from Arsenal went slightly under the radar in the summer window and the 21-year-old received the chance to warm up against his former club.

Tom Heaton is the third choice goalkeeper at United but he watched the Southampton game from the directors' box at Old Trafford while Graczyk took part in the pre-match warm-up.

Graczyk spent time on loan with National League South side Slough Town to gain senior experience in 2023/24 and signed for United following the expiration of his Arsenal contract.

The young shot-stopper joined Arsenal from Everton's academy when he was 14 and is expected to commit his international future to Poland, despite having been in England's youth system.

The experienced Heaton signed a one-year contract extension with United in July to spend another season with his boyhood club, and he will be 38 years old by the end of the campaign.

Heaton has been described as an ultimate professional. His career has spanned across two decades and he is a role model at Carrington, helping young players with advice.

United's goalkeeper department will receive a shake up if Heaton leaves or decides to hang up his gloves and there continues to be some uncertainty around the future of Bayindir.

Bayindir delivered a heroic display against Arsenal in the FA Cup, but his involvement has been sporadic during his time in Manchester and he continues to be linked with a move away.

Graczyk is thought to have impressed coaches and could eventually be promoted to the first-team on a permanent basis.
