We can say that the entire budget was spent during the Ten Hag period at Manchester United. The Dutch manager made transfers as if he was playing Football Manager and expected efficiency from the players. However, football is not exactly like that. Now, the Manchester United management has to adjust the budget for the Portuguese manager who was brought in to get rid of this difficult situation he left behind. It will be very difficult to adjust this budget because the value of the players bought during the Dutch manager's time has decreased. When they want to sell, they will sell at a loss. This will cause them to buy good players at high prices.
I am not a huge follower of Manchester United but let me ask, Didn't Manchester United Utilize Ten Hag era signing in the recent times or not?
People rush to blame the coaches, but I believe Manchester United have way much bigger problems than just those teachers. Cristiano Ronaldo tried to talk about it, but he was demonized and even booted out of the club
Until the atmosphere around United changes, they can bring in as many coaches as they can, but not much may change.
