Manchester United's manager, Michael Carrick, is likely to face a defensive crisis in their upcoming match against Chelsea at Stamford Bridge. Lisandro Martinez will be absent after receiving a straight red card for violent conduct against Leeds United's Dominic Calvert-Lewin. This disciplinary action follows a return from a five-match injury absence, making it a significant setback for the team. Additionally, Harry Maguire, who was also sent off prior to the international break, may face further suspension due to an FA charge related to his conduct after the incident. This leaves Carrick with only two senior centre-backs, Ayden Heaven (19) and Leny Yoro (20), available for the match. Journalist Steven Railston emphasized the importance of Maguire's recent contract extension, highlighting that despite being in the latter stages of his career, he remains the best defender in the squad. The upcoming matches against Chelsea, Brentford, and Liverpool will test United's defensive capabilities amidst these challenges.
