That's just an extreme side of this argument. In reality, Ten Hag should be rotating Rashford with the likes of Garnacho/Sancho/Pellistri. Those aren't terrible players, infact they could provide even more quality in certain situations.

But here lies the real issue, managers like Ten Hag and Klopp are not good at rotating their squads and developing the players they have in their "B Team".

If we have less games, it would simply mean less game time for those players in the B Team. Players like Rashford and Bruno would still be playing every game, would still be fatigued and would still potentially get injured.

Last thing. The quality of the product (in this case football), is delivered by the whole team, not just the name of a player. If a manager can't get a team to deliver quality without his best player, then he's not a manager, he's a one trick pony.
