Anders Lindegaard admits injury couldn't have come at a worse time for him in his Manchester United career.

Lindegaard is waiting on a comeback date after suffering an ankle injury in training just as he had ousted David de Gea from his first-team berth.

"It has been a frustrating time but that's how life goes," Lindegaard told MUTV.

"I don't know when I will be back, so I just have to keep smiling.

"It is the worst possible time for anyone to get injured."
