Manchester United's troubled season took another turn for the worse this morning as David Moyes' side slumped to a 2-0 first leg defeat to Olympiakos in the last 16 of the Champions League.
Argentine striker Alejandro Dominguez broke the deadlock at Karaiskaki Stadium when he got his foot to a shot from Yiannis Maniatis in the 38th minute and turned the ball past goalkeeper David de Gea.
First-half composure from the visitors soon turned to complacency after the break when striker Joel Campbell, on loan from United's Premier League rival Arsenal, caught De Gea off guard with a well-placed shot in the 55th minute.
Wayne Rooney produced no threat up front and strike partner Robin van Persie missed the visitors' only clear chance a shot over the crossbar in the 82nd minute as United slipped to its first defeat in the Champions League this season.
"This was a great victory against a massive club like Manchester. We were told to hold the midfield and we did,'' Maniatis said.
