#2 Building up slowly and playing more passes in the final third
United have been relying more on quick build-ups and counter-attacking moves in the last few matches, and that approach needs a change. The United forwards have struggled to control the ball while moving up with the frenetic pace, and therefore, failed to trouble the opposition defenders much.
They had 10 shots at the Barcelona goal in their last match, but none of them was on target. The likes of Lukaku and Rashford have worked hard but failed to be clinical in front of the opposition goal. As a result, the goals have dried up for United, and they should adopt a slower and more composed approach near the opposition penalty box.
If Pogba who has 14 goals and 11 assists this season already, plays as an attacking midfielder, he would be able to play more passes with the likes of Martial, Lukaku, and Rashford, and thereby exploit the gaps in the opposition defence. This would also allow the forwards more time on the ball. As a result, their shooting accuracy might also improve.
