Emery said: "It's giving us very big confidence on Sunday against Manchester United and the same with this performance and this victory. This comeback was very difficult but I think our reaction was a very good reaction from every player. Playing under pressure is good.
"Growing up under pressure, every player, like a team. And to feel difficult moments to give us our best performances in these moments. For us, today and Sunday, we were playing and being competitive. I think it's good confidence for us to feel that.
"After, if I am very demanding of myself, I want to take the best confidence with the ball, with the control with the ball with the possession, because I think against Manchester United and today, we lost a little bit these moments with the ball to give us the confidence with the ball and to control the match with the ball."
