Louis van Gaal revealed Luke Shaw was reduced to tears in the dressing room after suffering an "awful" broken leg during Manchester United's 2-1 Champions League loss to PSV Eindhoven.

The 20-year-old was on the receiving end of a thumping tackle from Hector Moreno early in the Group B clash, subsequently receiving seven minutes of treatment before being withdrawn on a stretcher while wearing an oxygen mask.

United confirmed the worst fears after the encounter, revealing Shaw would return to England for an operation having sustained a double fracture.

That news comes as a significant blow to the club and Van Gaal, who said on the BBC Sport website: "It is awful. The boy is in his second season and he has been playing fantastic. And now this happens.

"Shaw had an oxygen mask on and was crying in the dressing room. I hope he can play again this season.

"He is in hospital, he will be transferred with us, maybe, otherwise a day later and shall be operated in Manchester probably. It is awful."

Moreno went unpunished despite many deeming the challenge worthy of a red card and a penalty.

Van Gaal added: "You must judge for yourself. If I say it was a penalty and a red card then I am a bad loser. It was a very bad tackle."

Insult was added to injury for United as Moreno levelled Memphis Depay's opener before Luciano Narsingh netted a winner for PSV.

The manager said: "It is the same game as against Swansea [United's 2-1 Premier League defeat in Wales last month]. We dominate the game, create chances but we are not finishing."
