Manchester United vs Chelsea: 3 players to watch out for during the game at Old Trafford

#1 Harry Maguire

Harry Maguire in action - Stoke City v Leicester City - Pre-Season Friendly

Manchester United shelled out £80 million to secure the services of Harry Maguire from Leicester City this summer, making him the world's most expensive defender. The 26-year-old has been amongst the best centre-halves in the league for the past couple of years and will bolster Manchester United's defence, which leaked 54 goals in the Premier League last season.

The England international is expected to make his debut against Chelsea on Sunday and with a huge price-tag attached to his name now, he will have a lot of pressure on his shoulders.

However, the centre-half is not known to shy away from a challenge and will be keen to transform this Manchester United defence. Considering the firepower Chelsea boast in their ranks, Maguire will need to be on his toes, marshaling the rest of the backline.
