Oliver Glasner has revealed Crystal Palace targeted Manchester United’s system in their win at Old Trafford.
A brace from Jean-Philippe Mateta secured all three points for the visitors on Sunday afternoon.

The defeat is United’s 11th in the league this term as Ruben Amorim’s woes continue.
His tactics could now need altering after Palace’s approach in their impressive away victory.
Glasner was asked about his game plan following the match and whether he targeted United’s system.
The Austrian explained: “Yes, we did. Also, to be honest, we did it yesterday in training and it didn’t work so well. But I blame myself. I think I told them…
“I think it was maybe too much information we gave them during the week because I know that when we play against a team with 3-4-3 we know what we have to do. The players already know.
“Then Man United changed their build-up with dropping Bruno Fernandes into a back four and this sometimes happens because I think this can be a solution against a 3-4-3. But we were also prepared.
“We knew what to do. We showed them again at half-time and that was I think the key for the success. We didn’t give them the spaces they want to use.
“Yes, two or three times they found there are quick players in the pocket when they can turn and go one-on-one.”
United have lined up in Amorim’s favoured 3-4-3 formation since his arrival in November.
However, the Portuguese has so far only picked up 14 points from his 13 league matches in charge.
Match winner Mateta also commented on Palace’s game plan following his two-goal haul.
The striker revealed: “We know how they play with the new manager, we worked on a plan during the week and we stuck to the plan.
“We listened to the gaffer and worked hard and I think we deserve this win.”
Amorim’s tactical scare comes after he made another tweak for the visit of Palace.
Kobbie Mainoo started the match in attack as a false-nine, a change from his usual midfield role.
Meanwhile, strikers Rasmus Hojlund and Joshua Zirkzee were both left on the bench.
Amorim must also contend with a worrying injury to Lisandro Martinez, who was forced off against Palace.
The United boss admitted it was ‘serious’ after the match, but added he will know more in the coming days.
