Emery later said: "I'm very happy. Our reaction was fantastic. We are not 100% first in the group but I think normally we are going to win. We are settling with the players in this competition. At Villa Park with the supporters, we are playing very good.
"They were very focussed, very motivated. It was very tight to qualify for the next round. They needed a draw or a win. For us, it was important to try to win. We were consistent in our game plan. The second half, our control was better than the first half. We controlled it better. They had one chance off the cross bar.
"In 90 minutes, we had to try control everything. Today we score one goal through it and it's adding more qualities we can show."
