Manchester United defender Luke Shaw was taken off during the victory over Everton as a precaution after suffering a dead knee, according to manager Louis van Gaal.

Starting in just his second Premier League game for the club, Shaw appeared to be struggling with a knock during the second half of the 2-1 win over Roberto Martinez's side.

Despite trying to run the problem off, the 19-year-old was unable to finish the match and was replaced by Tyler Blackett in the 71<sup>st minute of the match.

Having missed the opening month of the season with a hamstring injury there was concern that the former Southampton starlet may have suffered a similar injury.

But van Gaal has eased fears over the defender's injury, telling BBC Sport: "He has a dead knee. He could have made it worse, so that is why he stepped out."

Shaw was named in the England Under-21 squad for their European Championship playoff with Croatia next week.

The full back endured a mixed afternoon against Everton where he gave away a penalty in the final minutes of the first half following a challenge on Tony Hibbert.

Goalkeeper David de Gea saved Leighton Baines' resulting penalty however, one of a string of impressive stops from the Spaniard, to spare his teammate's blushes.

Shaw showed his appreciation over the match, tweeting: "Wow David de Gea was unbelievable today. Thank you my friend for the penalty save."

After rescuing his side again with two stunning stoppage time saves, De Gea said: "I think we played a really good game. In the last 10 minutes they pressed a lot… but I saved the chances and I am happy.

"I think it is a good save. I didn't see the ball well, I just put my hand there."
