Which United moment most impressed Palace boss Glasner?

While being impressed by the speed and precision of the counter-attack that allowed Benjamin Sesko to plunder the winner, the Austrian enjoyed the enthusiasm and passion shown by Matheus Cunha, when performing his defensive duties.

The Brazilian had a tough battle against James Garner throughout, with the former Red performing excellently, but had a key role in the goal and worked hard to help Carrick's men retain the slender lead.

Late on, he displayed his joy at shepherding the ball out for a goal-kick, shortly before being substituted.

"We need confidence at Old Trafford," Glasner said at his press conference to preview Sunday's 14:00 GMT kick-off. "Manchester United are on a good run.

"I watched their game Monday night at Everton. It was a fantastic transition goal [from Sesko], and you can see the pace they have in their attack.

"On the other side, I also have seen that Everton caused them some problems, so I'm looking forward to Old Trafford.

"Of course, when Man United play at home at Old Trafford against Crystal Palace, it's the same: everybody there is expecting a win.

"Again, they are a very good team, they have a very good balance," he continued. "It's a very experienced team. When I see Luke Shaw, when I see Harry Maguire, when I see Casemiro, Bruno Fernandes, Matheus Cunha, Bryan Mbeumo - really very, very experienced Premier League players.

"And then I see [Amad] Diallo, I see Kobbie Mainoo - very, very young players with huge talent. It's a good mix they have now but I think the most important thing, for them, is they are consistently playing with their team and have a clear structure in the way they are playing.

"So this is what I could see against Everton and they have a great spirit right now, as I mentioned. For me, it was really impressive seeing Matheus Cunha celebrating winning a duel in their own box, because I think this is what Michael Carrick brought into his team."

As for Palace, their only team news update is Maxence Lacroix is expected to be fit enough to play again, despite being a doubt initially for the UEFA Conference League win over Zrinjski Mostar which has set up a tie against AEK Larnaca. 

"That's the big question," Glasner replied when asked about the centre-back. "I don't know but hopefully the goal helps a little bit! [He scored the opener on Thursday night at Selhurst Park].

"He did very well. Also defending was important, having him, also Jaydee [Canvot] played a very good game today and we needed his pace because they're quick up front.

"They will be the same at Manchester - they're so quick in their attack and then we need quick defenders, physically strong defenders. Right now, it looks okay but let's see how the reaction is."
