Wayne Rooney missed a penalty as the shock of the League Cup fourth round eventually arrived at Old Trafford with Middlesbrough beating Manchester United 3-1 in a shoot-out last night.
Championship promotion-chasers Boro had a goal disallowed when Kike hit the post and Daley Blind put the rebound in the own net, with an offside flag curtailing their celebrations.
Stewart Downing also forced a stunning save from Sergio Romero while Jesse Lingard hit a post for United but the 90 minutes finished goalless.
Neither side could break the deadlock in extra-time with Anthony Martial and Marouane Fellaini missing close-range headers at the death for United.
