Despite dominating most of the match, the Reds were beaten as Streller's early strike was added to by Frei's close-range effort in the 84th minute. Phil Jones' late header, his second goal in consecutive games after breaking his career duck at Aston Villa, proved insufficient as the hosts held out in injury time. United will instead compete in the Europa League for the first time and a night of misery was compounded by Nemanja Vidic's knee injury just before half-time with fears that the Serbian faces a lengthy spell on the sidelines.
Sir Alex opted to field Wayne Rooney in a lone striker's role and the Reds settled quickly despite the wet conditions. Ji-sung Park curled an early shot on the turn wide and there had been no real warning of what was to follow at the other end in the ninth minute. With Chris Smalling stricken on the ground with a head injury after a collision with Vidic, play was allowed to continue with Xherdan Shaqiri's driven cross only kicked out by David De Gea to Streller, who returned it with interest by smashing past the Spanish keeper.
