Manchester United boss Louis van Gaal says his side is difficult to beat when they play the way they did away at Crystal Palace.
Goals from Marouane Fellaini and Juan Mata helped the Red Devils move closer to a top-four finish.
They need three more points to be sure of Champions League football next season which they will try to get when they host Arsenal on May 17.
"We haven't played our best match but we have fought to the end," van Gaal told Sky Sports.
"It was very important to win this match and it is a right step to qualification for the Champions League.
"We had injuries, we had to change and the team was out of balance with Phil Jones at left-back and Wayne Rooney, our attacking point, going off. We have showed what you can achieve as a team and we have achieved our victory.
"Luke Shaw has gone to the hospital but I have good news because he shall go to the airport. It cannot be so bad otherwise he cannot fly.
"[Top-four?] You never know, we still have to win one point I believe. We have made a very important step.
"We have worked so hard, the players showed the team spirit is good. I am very proud. When you are fighting like this every week, we are difficult to beat.
"David de Gea did it several times this season, I am very happy he saved it [from Glenn Murray] because at the time it could have been 2-1 for Crystal Palace."
