Evans, who was captain for the night on his 100th United appearance, says all the players are keen to make up for what turned out to be a forgettable evening at Old Trafford.
"We're very disappointed not to be in the semi-finals," the defender told MUTV.
"I thought we would go on after we scored. And going into the first period of extra time, playing towards the Stretford End, I thought we'd have a chance of getting a goal and seal it from there.
"But they went down the other end and scored against the run of play really. We had a lot of possession but we couldn't break them down.
"A lot of our play was in front of them and I think the only way we were going to get in was down the side, but we didn't manage to do that as well as Manchester United can. We didn't get a lot of crosses into the box.
"The games are coming thick and fast and the manager will need his squad. So we need to pick ourselves up and hopefully win on Saturday [at Villa]."
