Manchester United head coach Ruben Amorim has promoted four academy players to first-team training ahead of Sunday's FA Cup clash with Arsenal at the Emirates Stadium.
The Red Devils will be aiming to build on what was a strong performance against Liverpool in the Premier League when they travel to London this weekend for an FA Cup showdown with Mikel Arteta's side.
Amad Diallo secured a point for Man United at Anfield, with the two teams playing out a 2-2 draw, but Amorim will consider making changes for the game against Arsenal, which comes ahead of successive Premier League fixtures against Southampton and Brighton & Hove Albion.
Jack Moorhouse, Tyler Fredricson, Godwill Kukonki and Elyh Harrison trained with Man United's first team on Wednesday, with Amorim deciding to introduce the youngsters into the first-team picture to take a closer look at them.
At this stage, it is unclear whether Amorim is considering including any of them in the squad against Arsenal, but Kukonki is believed to have been earmarked by the Man United head coach as a future first-team player.
Man United teenager Kukonki is said to be highly-rated by Amorim
Kukonki is a month away from his 17th birthday, but he has been on the bench on two occasions in the Premier League since Amorim's arrival, including against Newcastle United at the end of December.
The centre-back has made nine appearances for Man United Under-18s this season in the Under-18s Premier League, and he is believed to have made a strong impression on Amorim since the Portuguese's arrival in Manchester.
Harrison, meanwhile, is an 18-year-old goalkeeper, and he has recently returned to Old Trafford following a loan spell at Chester.
There is currently huge uncertainty in the goalkeeping department at the club, with Andre Onana and Altay Bayindir being linked with exits, while Tom Heaton only has a contract until the end of the season.
Amorim is believed to be keen to have a better understanding of the other goalkeeping options available to him, with Harrison therefore given the chance to make an impression during a first-team training session.
Moorhouse, 19, and Fredricson, 19, are also highly-rated, with the former nominated for the Premier League 2 Player of the Month award in December, while the latter has captained Man United Under-21s.
Is Rashford training with Man United?
Marcus Rashford did not train on Wednesday due to the illness which also kept him out against Liverpool, but the forward has not played in the Premier League since early December, having fallen out of favour under Amorim.
The 27-year-old's agent and brother has been in Italy this week holding discussions with AC Milan, and the Englishman is widely expected to leave Man United before the January transfer window closes for business. body check tags ::
