#1 Ole Gunnar Solskjaer and his team execute the perfect gameplan
Whether it was intentional or not, this was a perfectly executed game by Ole Gunnar Solskjaer. United started the game with high intensity, pressing hard for possession, and switching play quickly to areas around the box and looking to get an early goal. They got into the box and won a penalty due to Soyuncu's rash challenge on Rashford.
After the goal, United dropped their intensity a bit, still pressing for the ball but allowing Leicester City to keep possession and they looked to hit on the counter-attack with Ashley Young, Daniel James, Marcus Rashford and Juan Mata.
After the first half, Leicester grew increasingly threatening on possession and United dropped their attacking tendency and went all in to press and swarm Leicester's players. The Foxes were greeted with jostles, 2vs1 situations, hard tackles, and effective pressing by all of United's players.
However, staying back to defend with numbers and running around would have taken gas out of Manchester's players and Leicester would have caught them on that. Ole saw it and rectified it with two substitutions. Fred for Matic, and Tahith Chong for Juan Mata- fresh legs for aging and tired legs.
Tahith Chong's introduction changed the dimension for Manchester United. They now attacked effectively in addition to their pressing in defensive zones. Chong was oozing with flair and pace and ran riots in front of the Foxes' box. United got a chance or two to add to their tally too.
All in all - it seemed completely planned out and split up into phases. United's gameplan switched from phase to phase and yet one thing that remained common was effective pressing from every player on the pitch.
This is owing to Ole Gunnar Solskjaer.
