#2 The overlapping runs of the Liverpool fullbacks
Liverpool owe a considerable portion of their recent success to their expeditious full-backs. Both Trent Alexander-Arnold and Andrew Robertson are fast and very accurate with their crosses. They also play diagonal passes between themselves to build up quick attacks.
Alexander-Arnold is one of the best crossers in world football at the moment, and would always remain a threat to the United defence. United can not afford to play Luke Shaw as the left-back, as he is on the slower side, and would struggle to cope with Alexander-Arnold’s speedy runs. Brandon Williams should get the nod ahead of Shaw, and he too, would find it difficult to deal with the Liverpool right-back.
On the other side, Robertson combines very well with Mane and would try to create space by playing one-twos at times. United can think of counter-attacking with quick diagonal balls to exploit the space left behind by the Liverpool full-backs. It is easier said than done though, and much would depend upon the proper implementation of this strategy.
