Arsenal 1-3 Manchester United: 3 Reasons why United won | FA Cup Round 4

#2 Ole's tactical flexibility

Ole certainly seems to have more control over his squad than Jose Mourinho did

Manchester United's new man at the helm has brought about a great deal of joy around the club and for its supporters, as the Red Devils look to be back to their winning ways, winning the eighth game on the trot since Mourinho got the sack.

The new manager along with a bag of fresh ideas and positivity brought the priceless ability to alter his gameplan according to the players he has, not ask his players to do what they aren't best at like his predecessor did for much of his reign. All the players in the squad look like they've gotten a new lease on life. Even Alexis Sanchez looks kinda threatening again!

His use of substitutions is superb, and it proved to be the case again tonight, as second-half sub Anthony Martial restored United's two-goal cushion, leaving no hope in Arsenal's mind for a dramatic comeback.

United pass forward with intent and all the players are given roles that come naturally to them. In Ole Gunnar Solskjaer, United may have the perfect man to guide this current crop of United players to the absolute peak of their limits. The club's board must hand him the full-time job, as the baby faced assassin may have a few more tricks up his sleeve to pull for the club he loves so dearly.
