Oliver Glasner gives tense interview and digs out Crystal Palace board after frustrating Man Utd defeat

But United turned the match around in the second half, with Joshua Zirkzee and Mason Mount scoring to spark wild celebrations in the away end.

Glasner cut a frustrated figure during the contest, with the Palace boss visibly annoyed at his side's failure to hold onto or build on their advantage.

And it was a similar story following the match, with the 51-year-old saying: "I don't want to talk about the missed chances.

"If we need more than one minute to be organised for a free-kick, it is our fault.

"How we scored is a penalty. It is how it is. We deserved to have the lead and then it is about small margins.

"I can't remember if Manchester United had a chance in open play but they were really good from set pieces and that's why we lost in the end.

"We can find many excuses, we can say fatigue, rotation, many excuses but the performances in many parts was good.

"Man United have played 50 per cent less games this season. The result hurt, really hurts at the moment but we will learn from it.

"Sometimes learning hurts. We missed a couple of chances in July and August, in the transfer window, to make it easier for us but again we will stick together and make it better."

With the January transfer window creeping closer, Glasner also suggested that his side had left it too late to add to their squad following a quiet and underwhelming summer.

"If you play European football for the first time in your history, you should invest and not save," he added.

"We are doing well, we are still in a good position in the league and in all four competitions.

"I think January is too late. We will have played more than 50 per cent of our games. Ismaila [Sarr] we lost him today with an injury and also he goes to AFCON so everything we are facing now, it's not surprising.

"Everything was pretty clear and I didn't say anything but today I think it is also time to speak about it that we missed the chance to play an even better season in the summer."

While it was a difficult day for Palace, it was a huge win for United.

And Ruben Amorim was left delighted, with the 40-year-old getting a big response from his team following their shock 1-0 defeat to Everton at Old Trafford on Monday.

He stated: "It was small details that helped. The pace and intensity was better in the second half.

"I could see that Palace were getting tired at the end of the first half and knew they would suffer if we scored.

"We went on to control the game well away from our goal and in the opposition half. We controlled the game well but just have to be careful about what we did in the first half.

"In this moment I just want to evaluate our team. We need to evolve and create variety in how we build-up - that's the most important thing."
