Wait, what do you want to mean in this case because I think the issue of trust has nothing to do with the current injury problem and it is not logical to say that Manchester United's injury storm this time is related to Ten Hag's trust in players.
At the moment investigations are continuing into how training or some of the facilities at Manchester United but it is said that the provisional reason that can be concluded to this day is the high volume of matches last season and the schedule that changed a lot because of the world cup although this cannot be fully used as an excuse because if it is the main reason the players at other clubs should also feel even though many must have complained about the world cup and the schedule that seemed forced.
Well there are many things i think would contribute to the numerous injury rate at the team, like poor training facilities, incompetent medical team as well as the busy schedule they had last season that's affecting most players forn this season, however we're yet to know any news yet concerning the investigation the board is carrying out concerning the injuries.
Well the busy schedule is the major reason why a lot of players are getting injured lately, it's not only about Manchester United but alot of players from different teams have sustained severe injury that's kept them away from the team for half of the season and the players are already complaining how the busy schedule is affecting them, i think this is something the footballing authorities should look into.
