Emery was pleased after defeat at Arsenal on the weekend.
“It was a very fantastic response from the players here away against Crystal Palace,” he said.
“We were winning a lot of matches but how we competed today as well was really fantastic. We dominated the first half, had chances to score and didn’t concede a lot.
“In the second half, we started with the same idea and started dominating again. We lost 15-20 minutes when they pushed, creating some chances to score.
“In that moment we were struggling, but we reacted fantastically in the last 20 minutes and created chances, hitting the post through Ollie Watkins, a very good opportunity for Morgan (Rogers) and Emiliano Buendía.
“We competed fantastic. In this match we were closer to winning but we drew, and we must accept it. How we are overall in the table on day 21 is fantastic.”
