Manchester United manager David Moyes has insisted that he must take full responsibility for his side's shock 2-0 defeat to Olympiakos in the Champions League tonight, before declaring that the last-16 tie is still alive despite a dreadful night in Athens.

United slipped to their first loss in the Champions League this season to the Greek champions in a lacklustre display, with goals from Alejandro Dominguez and stunning Joel Campbell strike giving Olympiakos a strong lead to take to Old Trafford next month.

The Red Devils had shown signs of revival at Crystal Palace last weekend in a 2-0 victory, but that performance will seem a distant memory to United fans tonight after being outfought and outworked by Olympiakos for the vast majority of the first leg.

Moyes offered no excuses for his side's disappointing efforts and admitted that they deserved to be beaten, before attempting to find a silver lining by making it clear that the tie is far from dead.

He told BBC Sport: ''That's the worst we've played in Europe, we didn't deserve to get anything. We didn't offer enough on the night to create a goal.

''I'm surprised, I didn't see that level of performance coming. I take responsibility, we have to play better.We can do, and the one thing is there's still a second game to come. There is a second game and we will do all we can to turn it around. The players are hurting.

"There is undoubtedly talent at Manchester United but we didn't show it tonight. We are determined to put it right and we have the opportunity to do that. The players are hurt."

While there was a touch of fortune about the opening goal United conceded Campbell's quality effort in the second half was sensational, with the Arsenal loanee curling in a wonderfully-placed strike on 54 minutes from outside the penalty area.

United struggled to create opportunities throughout the 90 minutes but did spurn one gilt-edged chance in the closing stages, with Robin van Persie lashing over from close range despite having time to pick his spot.

Moyes and his boys now face a huge test of character to keep their fading European dream alive at the Theatre of Dreams in three weeks, particularly with hopes of Champions League qualification via a top-four finish looking increasingly slim.
