Manchester United manager Louis van Gaal has expressed his delight after the 2-1 victory over Crystal Palace but confirmed both Wayne Rooney and Luke Shaw were force to leave the pitch due to injuries.

The Dutch boss replaced the left-back with Jonny Evans in the 40th minute while Radamel Falcao came on for the captain at half time.

The manager explained the substitutions after the game and confirmed that even though Shaw went to the hospital his injury is better than first thought.

"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," Van Gaal said.

"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."

After three consecutive defeats to Chelsea, Everton and West Bromwich Albion, the Premier League giants secured three crucial points thanks to Juan Mata and Marouane Fellaini's goals and need just one win from their final two games to secure qualification for the Champions League.

Though Liverpool, who visit Chelsea on Sunday, are now seven points behind, Van Gaal is unwilling to take a top four spot for granted.

"I am very happy with the result and it brings us a step closer to our goal. Now we will see [on Sunday], with a fantastic glass of wine, the result between Liverpool and Chelsea."

"But 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 so goo. I am very proud. When you are fighting like this every week, we are difficult to beat."

"We haven't played our best match but we have fought to the end. It was very important to win this match and it is a right step to qualification for the Champions League.
