Injury update: Crystal Palace v Manchester United

Valencia suffered a foot injury during last Sunday's Manchester derby at Old Trafford and did not feature in the Capital One Cup penalty shoot-out defeat to Middlesbrough on Wednesday night.

Wilson made his first start of the season in midweek but left the action for Wayne Rooney at half-time, while Memphis played for 71 minutes until he was replaced by Anthony Martial. 

"Willo was injured but also Memphis Depay was injured," van Gaal told MUTV on Friday. "It was a very bad game afterwards because we lost on penalties and also we lost two players. We have to wait and see [how long they are unavailable for] because it was only two days ago."

Meanwhile, Ashley Young is edging closer to full fitness after stepping off the bench to replace Marcos Rojo in that same cup tie. The versatile midfielder had previously missed three first team matches with an injury picked up in the 3-0 loss to Arsenal at the Emirates Stadium. 

Paddy McNair is still recovering from a serious injury that he sustained while playing for Northern Ireland in the recent international break and, of course, Luke Shaw is still a long-term absentee with the double fracture of the leg that he sustained in the Champions League defeat at PSV Eindhoven.

MUTV will show the full, exclusive interview with Louis van Gaal in Countdown to Kick-off at 18:30 GMT on Friday.
