Manchester United's coaching staff believe their squad has too few vocal leaders and that the injured Lisandro Martínez has been sorely missed in that regard.
The defender has been unavailable for 37 of United’s 48 games this season owing to foot, knee and calf problems, including Monday’s humiliating 4-0 defeat at Crystal Palace. The Guardian understands Erik ten Hag’s coaching staff have noticed how much quieter the changing room is in Martínez’s absence and believe this had been detrimental to performances and results.
