It was a frustrating night for United who pressed and dominated possession but struggled to hurt their opponents.
United, however, will qualify for the last 16 if they beat group leaders Wolfsburg in their final game on December 8. United skipper Rooney: "It is a game we were capable of winning and we played some good stuff in the first half and we were unlucky not to go in up at the break.
"In the second half we showed a lack of composure so that was not great, overall a draw was probably fair but this is what we did not want.
"Going to Germany is always tough, we have to believe in ourselves and have confidence we can do that, it's not the way we wanted but that is the way it is and we have to believe we are good enough to get three points.
"We are not ruthless enough - we have to score more goals as a team, they were able to nearly hit us on the break a few times. It's a learning curve but we cannot go on saying that. We have to change these games into victories."
United boss Louis van Gaal admitted his side lacked a ruthless streak. "We could have finished it off in the first half but also in the second half, to the end we're not so good any more, we were afraid to play the ball but nevertheless do not give too many chances away," said the Dutchman.
"The midfielders were dropping too much and that is why we didn't support too much our front players.
"We have created in one half three open chances but they were difficult chances.
"I cannot say every game in the interview with you that we didn't finish but it is the truth.
"It will be very difficult because Wolfsburg are the best team in our group to play against, but it is possible.
"We have won also at home and PSV has to win against Moscow, it is not so easy."
United defender Chris Smalling said: "We had more than enough chances to win the game and make the difference in the final game.
"Coming in we saw Wolfsburg as the toughest game - and we have given ourselves a lot of hard work. We needed to move the ball quicker. We go there with hope because we have beaten them here."
