Don't forget that Erik ten Hag is also one of Pep Guardiola's students. because at the beginning of Erik ten Heg's career in the world of coaching, we know that Erik ten Heg was a coach at Bayern Munich II for two years. And at that time Pep Guardiola was the coach of the Bayern Munich first team. So Erik ten Hag learned a lot from Pep Guardiola at that time. And this is what makes Pep Guardiola a great coach. And he is indeed a role model for all coaches in the current era. And now there are many young coaches who are successful in managing their clubs thanks to having learned from Pep Guardiola and the most famous is Arteta, who was Pep's assistant for quite a long time before Arteta finally became Arsenal coach.
Ten Hag big ego seems to mean that he often doesn't listen to Guardiola instructions at that time, so now he is having difficulty getting Manchester United back up in my opinion, the quality and training scheme implemented by Ten Hag in the Manchester United squad right now doesn't look like no be Guardiola student for a long time, in my opinion, Manchester United game looks far from perfect and even if we look at the style of play, it is much not like Manchester City game so far, indeed every coach has a different coaching style and scheme from one coach to another, however if Ten Hag is Guardiola student, of course we can at least see little the characteristics of Guardiola game in Ten Hag tactics so far.
Rather than ten hag, of course Arteta can be said to be the strongest in adopting Guardiola game so far, but even though he is still young, I think Arteta is a smart coach because he is able to combine the total attacking game that Wenger has been using and also the tiki taka that has always been is a characteristic of Guardiola in my opinion, Arteta is a coach who has succeeded in gaining knowledge from these two coaches and applying it so far at Arsenal squad.
