David de Gea escaped serious injury when he hurt his knee ahead of Manchester United's Europa League match last week.

De Gea had been withdrawn from his team's 2-1 defeat in the first leg of that Europa League contest after feeling the problem during the warm-up to the game.

The incident at Midtjylland had occurred while De Gea was making what looked like a routine save, then he went back into the dressing room for treatment.
