Manchester United striker Will Keane is set to go under the knife.
Keane is to undergo surgery on a groin problem sustained in the Emirates FA Cup tie at Shrewsbury Town last month.
The 23-year-old forced his way back into the first-team reckoning and came on as a late substitute at Sunderland before replacing Anthony Martial after 71 minutes of the 3-0 win at Greenhous Meadow.
Louis van Gaal has confirmed Keane requires an operation and, frustratingly, faces another spell on the sidelines.
“I have to rotate so, with Marcus Rashford, I have more players who can play in the striker’s position,” he said.
“I have Wayne Rooney, Anthony Martial, Rashford – I had Will Keane but he is injured and shall be operated on.
“So, when I have more players, I can rotate more and justify that.”
