'When you give the top teams a crumb, they take the whole cake'
Crystal Palace boss Oliver Glasner has been speaking to Sky Sports after the defeat: "In football, sometimes it's crazy. When I compare the performance in the first-half, to [how we played at] the Emirates [in the Carabao Cup], it was far better today. But we were 3-1 down, and over there we had the lead, so it's crazy because I thought we did many things well.
"The first goal was a cross, the second was a set-play and the third was a cross where we don't mark the man. We defended the box terribly and the quality of their players they punished us. If you want to beat a team like Arsenal, everything has to be almost perfect, it was not good enough today.
"We created chances but the result is disappointing. In the box, there were too many times where we watched the players."
On failing to take their chances: "When you concede five goals, it is unlikely you get a point! But yes, at 2-1 down we had a big chance and before they scored a third goal. We had big chances in the second-half, then they scored the fourth and the game was over.
"We lost the belief to come back again, but we gifted them the goals and it's not easy to come back.
"From the first 60 minutes, we can take a lot of positives. We have to defend the box [better] but everything else was one of our best performances. The pressure we gave them, the balls we were winning in possession, how we move the ball and how many chances we created.
"Of course we will learn from it. We have to learn that when you give the top teams a crumb, they take the whole cake!"
