Liverpool are preparing to host Manchester United in Thursday night’s crunch clash at Anfield in the Europa League as they look to take a step towards booking their place in the quarter-finals of the competition.
Manchester United have won their last four Premier League fixtures against Liverpool since a humiliating 3-0 home defeat in March 2014.
Liverpool, meanwhile, are unbeaten in eight European games this season, and have not lost in six Uefa home matches.
They have not lost in eight Uefa Europa League home fixtures since a 3-2 defeat by Udinese Calcio in the 2012-13 group stage.
