#3 Fluid attacking set up
Solskjaer likes his team to have a certain degree of flexibility. It was an important attribute that he incorporated into Manchester United since taking charge. Against Watford too, Solskjaer stayed true to his system and it helped him gather three important points.
United started with Martial, Rashford, and Mata, who floated around the front line. When Mata shifted to the False 9 role, he was warranted a lot of freedom in his movements. As United gained confidence in the first half, they moved the ball very fast around the opposition box, finally scored through a counter.
In the second half though, United’s clever movements were fruitful again. Martial took a ball from the left side and after a few swift interchanges, found himself at the end of a cut back from Lingard from the right. Foster saved well from the Frenchman's first effort, but Martial was off the ground in a flash to lift the ball home from close range. It helped United settle down and ultimately sealed the game.
