A 96th minute penalty converted by Jean-Philippe Mateta earned Palace the point on the day.
"It looks like I don't know what I'm talking about," joked Glasner. "Even managers can be wrong. I was convinced that this would be a completely different game, but they were so efficient today, they had eight shots and scored three goals.
“We played so well, our attacking was incredible. It was one of our best attacking performances (during Glasner's time at Palace).
“We can be pleased with how many problems we caused them, how many attacking situations we created, how many goals we did score. But also how many goals we could have scored.
"It just showed how good we were today."
The manager also said: "Even at 3-3 we had a great chance to win it, with JP (Mateta). But what I loved in this situation is that Eddie Nketiah... he could take this shot and say 'I want to be the hero and make it 4-3.' But he plays an unselfish pass to JP.
“This is how we work together, how we play together. And overall, I’m really pleased with this performance and I’m really proud of the team.
"I'm proud of how they kept their belief and how hard they worked to get this point."
