Manchester United manager Ruben Amorim knows the scale of the task at hand when his dysfunctional team face Arsenal in Sunday’s Premier League clash. 

The Portuguese coach has struggled since succeeding Erik ten Hag at Old Trafford in November. The Red Devils languish in 14th place in the Premier League table and are out of both domestic cup competitions. They now face Mikel Arteta’s high-flying side that recently hammered Dutch champions PSV 7-1 in a midweek Champions League clash.
