Moreno will face United again in midweek as Van Gaal's side look for the victory which will stamp their passport into the knockout stages of the competition.

It's touch and go whether the England left back plays again this season , meaning his European Championship ambitions for the Three Lions next summer are also in serious doubt.

Mexican defender Moreno's tackle - deemed reckless by the Manchester United boss - in the earlier Champions League game between the two sides in Holland, led to Luke Shaw being rushed to hospital with a severe double break of the right leg.

"We have all seen the tackle. He was going for the ball, but he didn't just get the ball. It was a lousy tackle."

But Shaw's continuing absence is a problem for Van Gaal who revealed that he could be in the market for a left back in the January transfer window.

"I was convinced that he would have a very good season. Shaw was the main player for that position is it was a big blow for us."Van Gaal added.

"Maybe we have to buy a left-back in January. His rehabilitation is going well, but the process can now be very slow.

"That's when you need a very good mental character to continue. I don't know if he will play again this season because we don't know if his recovery will continue to be quick and the doctors won't take any risks, which is good."
