Rooney suffered the injury mid-February, with reports suggesting he could be out of action for up to two months.
When asked about the subject in his pre-match press conference ahead of the clash against Watford on Wednesday, van Gaal simply said: “Rooney is still in a brace.”
Rooney had been one of United’s best players in 2016 prior to his injury and his absence came as a blow.
While Rashford has burst onto the scene as of late, van Gaal will be keen to get Rooney back on the pitch as soon as possible. Rooney’s leadership and experience could prove to be invaluable as United look to make a success of their campaign.
