Pogba's absence will affect the team's gameplay. Pogba is a great midfielder. Although his performance in the last few matches was not good, not only Pogba but also the performance of any player on the team was not enough good. Today, Manchester United has to play well as a team. If they sort out the game plan depending on a particular player they can't win.
His presence sometimes bring troubles to the team he is playing for too. It happens multiple times in Manchester United and in Euro 2020, the carelessness of Pogba caused the equalizer of Switzerland. The rest in that match, you know already.
Pogba is a great attacking midfielder but playing with him is dangerous and Manchester United now don't have a good defensive midfielder who can save them. Pogba after his good start in this season, 7 assists in 4 matches, after that he did not contribute to any other goal. He is in bad form.
I think Arsenal need to be able to defend against Leicester's counter-attack with their quick counter-attack there can be no complacency on the other hand Arsenal as an away opponent will play the same attack but it's tough Leicester are not a weak opponent even behind all this could be a defeat for Arsenal.
I don't believe in the defense ability of Arsenal so I think if Arsenal plays as they are better team, they will be sniffed by Leicester City.
You are right about the counter-attack ability of Leicester City. They are too good at this and Vardy still plays too good at his age. That is a surprise.
