Palace won 2-1 thanks to goals from Jean-Philippe Mateta and Tyrick Mitchell.
Glasner said afterwards: “I think we played a very good first half, controlling the game. We had a big chance straight after half-time (when Maxence Lacroix headed against the bar), and then all of a sudden it's 1-1, and the momentum changed. West Ham were better for 15 minutes after the equaliser, but I think then credit to the players that we could turn the momentum again.
“It was a deserved win. We know of T Mitchell. We have to be careful because we are really in a great run. Maybe the only criticism is that we didn't kill the game when we could kill it. This is a little bit the story of this season until now. On the other side, it's good, we're still unbeaten, we have the second away win, so it's all on track.
“I also told the players that when I watch our game, I see many, many positive things, but I still see a lot of potential we have – so it’s good. Now, it's looking forward to one week of training, the first (full) week of training with this squad, and preparing for the Liverpool game.”
Glasner continued: “I praise them so often, I can just repeat it. I think this is the result of our good results, not just for two weeks, but really for months now. The players believe in what we are doing. Football is a game of momentum. I've seen not so many games where it's 90 or 100 minutes always just going into one direction, especially when we play away here at West Ham.
“Then it's just keep calm, defend well, and this is what we're doing really well for months now. It's not so easy to create chances against us, and then we will create chances again. It can be transitions, we move the ball very well in possession, especially into the final third."
