The problem is not finding someone as Pep because if I’m not mistaken Pep also had flaws at some extend coaching the team but he worked on himself. Self improvement is so special and Pep is a perfect example of self improvement every season, now my question is Ten Hag ready to work and improve the team obviously I already know my answer. If Manchester United should employ a new coach I hope they find someone better than Ten Hag that will be able to restructure the team.
Almost all coaches have shortcomings and that is human nature but Pep Guardiola has the advantage of seeing the potential of players to be placed in the match. Pep Guardiola knows what the team needs so he doesn't try to do something that makes his team lose. Just look at how when he replaces a player and it is done if it is needed, not because the player made a small mistake in the match and he gives each player the trust to develop themselves to be better.
Erik Ten Hak may be different because he often tries to change strategies and places players who are not in their position. So what happens is that it doesn't give a better effect because the players don't know what to do and maybe this is the reason why Erik Ten Hak has difficulty developing the team to be stronger.
