Olympiakos' Alejandro Dominguez, left, fights for the ball with Manchester United's Michael Carrick during a scrappy start to the match. Dominguez has had the best chance to open the scoring so far, when, in the eighth minute he charged through the United defence but was denied by a brilliant sliding block by Nemanja Vidic Photograph: Thanassis Stavrakis/AP

Seven minutes before half-time Olympiakos take the lead when Dominguez sticks out a foot to divert Giannis Maniatis' wayward shot towards the opposite corner, totally wrongfooting David De Gea, who can't react in time and the ball trickles over the line Photograph: Aris Messinis/AFP/Getty Images

Dominguez has every reason to celebrate he reacted so quickly and adroitly to give his side the lead with a very nice goal indeed.= Photograph: Yorgos Karahalis/Reuters

There's more joy for Olympiakos' players and fans early in the second half when Joel Campbell doubles the home side's lead with a delightful strike. The youngster, who is on loan from Arsenal, poked the ball through Carrick’s legs with a delightful touch, sized up his options and then bent an outstanding left-footed curler past De Gea’s despairing dive and into the bottom-right corner from 25 yards. Brilliant. Photograph: John Sibley/Action Images

With eight minutes to go United fashion their first decent chance when Shinji Kagawa slips a pass behind Holebas to Chris Smalling, who instantly knocks the ball into the middle the unmarked Robin Van Persie.

Rooney rightly applauds the United fans who made the long journey to watch such a poor performance. The tie isn't over yet but United have left themselves a big job to do at Old Trafford in the second leg. Final score: Olympiakos 2-0 Manchester United Photograph: Aris Messinis/AFP/Getty Images
