The Eagles were the better team from minute one to minute 90 at Selhurst Park, securing a first-ever league double over United with goals from Michael Olise (two), Jean-Philippe Mateta and Tyrick Mitchell – and it could have been more on a memorable night for Palace.
Glasner told Sky Sports: "Congrats to the team for this win, and for this 4-0 at home to ManchesterUnited.
“I think the first-half, we didn't really play as well as we could, so it was not that consistent. In defence we opened the middle too often and they could find the pockets and we had a little bit of a problem, but we were very efficient, so we scored very nice goals.
“But, at half-time, we made two or three adaptations, the players listened again and in the second-half, we were much better and were in much more control of the game. We created a lot of chances, we scored nice goals, but we were a little bit more consistent in our basics and so it's a great win, and congrats to the team.
“Congratulations – but always stay humble. We know it is not so long ago where we struggled with relegation, just five points away, but now we've found ourselves and the players have confidence. That is what we want to read. We are doing well, but we still have a lot to improve.”
