Manchester United and Liverpool have both been charged by UEFA following crowd trouble at their Europa League clash at Old Trafford, the governing body announced on Friday.

Five men were reportedly arrested following the disturbances on Thursday which saw rival fans fighting in the stands and flares and objects thrown.

Liverpool knocked Manchester United out of the second-tier European competition after their last 16 second leg ended 1-1. That gave Liverpool a 3-1 victory on aggregate and a place in Friday's quarter-final draw.
