Boss Louis van Gaal says Manchester United can still qualify to the next round of the Europa League despite suffering a surprise 2-1 defeat at FC Midtjylland.
Regular goalkeeper David De Gea had to sit out the game after suffering an injury in training with the Dutchman confirming that he will be assessed in the early hours of the morning.
"After 10 or 15 minutes we controlled the match, we scored a goal but we also gave a goal away," van Gaal explained.
"One minute before half-time and that is a difficult time to concede a goal. In the second half I have to say that Midtjylland were winning every ball and that was very disappointing because you know in advance that this is the key to this game.
"Then they score, and when you see how they score it is a little bit unnecessary in my opinion. But still we have a chance [to go through in the tie] I think.
"We have to speak about why our players were not capable of winning the second balls, to keep the ball in our possession, because we had a lot of unnecessary losses of the ball.
"Now I can only analyse that Midtjylland were winning these second balls and then you can expect they will score out of a few chances. But we could have scored also, Jesse Lingard could have scored two times I think. In spite of that we could have also finished the game.
"[Injuries?] I think it is the law of Murphy, when you have a list of 13 injured players and a few minutes before the game we can add another player to the list. Then it is difficult to cope with such a list of injured players.
"It [David De Gea's injury] happened in the warm up. We have to wait and see for the scan tomorrow, then maybe we can say more but it was a big surprise."
