Nick Coppack reviews each player's performance...
David De Gea An unhappy return to Spain, although he'll be pleased enough with his individual performance. No chance with either goal and made a handful of top second-half saves.
Rafael The young Brazilian was given a torrid time by Iker Muniain, who looks one of Europe's top young prospects. A tough outing.
Jonny Evans Often left exposed after United's full-backs had gone forward, Evans had to do a lot of "mopping up". A thankless task on an evening to forget for the Reds.
Rio Ferdinand Gave up a yard of space for Athletic's opener but was otherwise solid enough at the heart of defence. Replaced midway through the second half after picking up a slight calf knock.
Patrice Evra Pegged back by the lively Markel Suaseta for much of the game, Evra struggled to make his mark. A difficult day at the office for the Frenchman.
Ji-sung Park Not even the South Korean, usually so effective at breaking up attacks, could stem the Athletic tide. Saw little of the ball in possession.
