The Red Devils have made an average beginning to the top-flight campaign Wade Boggs Jersey and they have accumulated just from the opening six matches. In comparison, the Gunners have acquired in the same period, but they have likewise produced a mixed bag of performances with their defence continuing to remain a point of weakne s. Ahead of the Premier League meeting between two of Englands most succe sful sides, we look into three players, who could leave their mark on the game.Three key players to watch for:Mason Greenwood Manchester United: The 17-year-old has been the standout player for the Red Devils of late and he has scored in each Joe DiMaggio Jersey of his against Astana and Rochdale.

Mariano Rivera Jersey Nicolas Pepe Arsenal: The Ivory Coast international had a positive performance in the over Aston Villa and he managed to score his maiden goal after Pierre-Emerick Aubameyang handed him with the chance to convert from the penalty spot.

The left-back did not have much defending to do on the night but overall, he had a good performance, where he made several overlapping runs to provide deliveries in the box. Should Tierney start on Monday, the Gunners will have an efficient option to deliver cro ses towards the likes of Pierre-Emerick Aubameyang but that would still depend on whether he can outcla s Aaron Wan-Bi saka, who has been one of the leagues best Babe Ruth Jersey right-backs with an per game.
