Manchester United could hand a debut to £37million teenager Amad Diallo when they face Liverpool in the FA Cup fourth-round at Old Trafford on Sunday.

Ole Gunnar Solskjaer is set to make changes for the second meeting with Liverpool in eight days and while Diallo is unlikely to start, the 18-year-old may be set for a place on the bench.

Diallo completed his move from Atalanta to United this month and the winger has impressed in first-team training. With nine places available on United's bench for the cup tie and the opportunity to use five substitutes, Diallo may get his first taste of action for his new club.

There is plenty of excitement around the diminutive attacker, with United committing £19million up front to sign him from the Serie A side despite the fact he has only played 76 minutes of senior football at that point. The deal was completed in the summer ahead of a January arrival, with Diallo playing 46 more minutes for Atalanta this season before making the switch to the Premier League.

That tally could increase today, however, with Solskjaer hinting he could be included in the squad to face Jurgen Klopp's side.

"We've not decided yet . He's still training and he's been training a lot but he might be involved," he said.

It would be a grand stage for Diallo to make his United bow. These clubs last met at this stage at Old Trafford in the treble-winning season of 1998/99, when United scored twice in the final two minutes to overcome Liverpool, who had scored early through Michael Owen.

Dwight Yorke equalised before Solskjaer's late winner sent Old Trafford into ecstasy.

"Ah, it was an unbelievable feeling and I think you can see that by the celebration after as well. That was the first goal I scored against Liverpool and it was a big one," said Solskjaer.

That late comeback set the tone for a season that would be full of them, before another injury-time goal from Solskjaer secured the treble in the Nou Camp in May.

"We had some tight fought games and a few moments like that in the FA Cup. Probably the moment for me is when Peter [Schmeichel] saves the penalty from Dennis Bergkamp, probably that was the defining moment for the run-in to the season," added Solskjaer.

"But we had just started on the undefeated run, after we lost to Middlesbrough [in December], and of course it was a big game against Liverpool and it looked like one of those games where you weren’t going to score.

"I think Keano hit the post a few times and then we had some massive chances and then I stole the ball off Scholesy. That (goal) was actually my only three touches in that game. I had two to settle and one to put it through Carragher’s legs."
