A look at the statistics for the 2021-22 Premier League season shows the Red Devils have had the third-lowest success rate when pressing their opponents.OptaJoe@OptaJoe-43 - During the month of November so far, Manchester United (17) have attempted the fewest shots in the Premier League, whilst also facing more opposition attempts than any team (60).

Crossroads. https://t.co/NtlwzmyPCSOver his 30-year coaching career, Rangnick has pioneered geggenpressing. The intense, high-octane, all-action brand of football has been popularised by Jurgen Klopp and Thomas Tuchel.Manchester United's recent 1-1 draw against Chelsea highlighted the difference between the two teams. While the Blues pressed as a team, United appeared disjointed and inconsistent while pressing their opponents, with Bruno Fernandes often leading a one-man charge.With Rangnick set to make changes, here are five Manchester United players who could see reduced playing time under the German coach.#5 Scott McTominayManchester United's Scott McTominay (left) squares up against Chelsea's Antonio Rudiger.Manchester United's double pivot in midfield was a constant point of contention under Ole Gunnar Solskjaer. While Fred has turned in a couple of improved performances this week, Scott McTominay had a good game against Chelsea.United Zone@ManUnitedZone_Roy Keane : “They just toyed with United. So poor. Men vs boys. Foden said it’s a tough place to come - it’s not. It’s just so poor. McTominay, Fred - these players aren’t good enough for Manchester United.” #MUFC8:11 AM · Nov 6, 20216196836Roy Keane : “They just toyed with United. So poor. Men vs boys. Foden said it’s a tough place to come - it’s not. It’s just so poor. McTominay, Fred - these players aren’t good enough for Manchester United.” #MUFCUnfortunately, the positive display can't mask the fact that McTominay isn't as mobile as Fred nor is he proactive enough in possession. Rangnick's tactics require his teams to press high up the pitch and move the ball forward.McTominay is one of Manchester United's own, having come up through the academy. But at 24, he is no longer a youngster. The midfielder's penchant to settle for square passes and limitations in possession could see him dropped for Donny van de Beek or Jesse Lingard. Both of them are waiting on the sidelines.#4 Harry MaguireManchester United captain Harry Maguire has had a torrid few weeks.Harry Maguire has been through a lot over the last month, and his situation is unlikely to become any easier under Rangnick. It began with a series of high-profile individual errors against Leicester City, Liverpool and Manchester City that led to United conceding and losing all three games.To exacerbate matters, the club captain's dismissal during the 4-1 hammering by Watford rang the death knell for Solskjaer's time as Manchester United boss. Rangnick is unlikely to display his predecessor's patience with the world's most expensive defender.SPORTbible@sportbible"Harry Maguire • £80 Million Pound Superstar." 😲Set to the music from ‘You’ve Been Framed’ the video highlights ever mistake Harry Maguire has made in a Manchester United shirt. 👀sportbible.com/football/footb…12:16 PM · Jun 21, 202022416"Harry Maguire • £80 Million Pound Superstar." 😲Set to the music from ‘You’ve Been Framed’ the video highlights ever mistake Harry Maguire has made in a Manchester United shirt. 👀sportbible.com/football/footb…Along with his leadership, Maguire has also been criticised for a rather obvious lack of pace and mobility.Rangnick usually deploys a high defensive line, with centre-backs pushing all the way up to the halfway line while the team has possession. Maguire and Lindelof do not have Raphael Varane's pace, and could struggle to recover quickly while defending counterattacks.Under Rangnick, Eric Bailly could be Varane's new defensive partner, or Manchester United might even look to sign a new centre-back alternative.
