Both players would likely have started had they been fit so their absence at Anfield will come as a blow to van Gaal.
“I don’t think they are fit to play, but maybe on the bench. I have to see how they are,” van Gaal told reporters this afternoon.
Blind produced a fine performance against Spurs in the position and fans will be hoping for more of the same from the Dutchman.
On the flip side, a club of United’s stature should not really be relying on a midfielder to occupy a defensive position.
Van Gaal is reportedly looking to add some depth to his squad, with Wolfsburg’s Ricardo Rodriguez linked with United in recent weeks.
