I cannot agree with you. No team can play well only if the squad is strong. We have seen the situation of Manchester United. The performance of this team was very poor until Ten Hag became the coach. Ten Hag gradually stabilized this team. On the other hand, we can look at Ligue 1 team PSG. The three best strikers in the world Neymar, Messi, and Mbappe were in their squad. Also, almost every player in the squad was a star player. However, the team's performance in the Champions League was poor. PSG didn't lack money, their squad was strong. So why this team did not play well in the Champions League???
Ten Hag made a lot of changes to the team before a good result followed, and by the way, he very significantly updated the squard of the team. As for PSG, tell me who was the coach of these star players, who is Galtier, who even knew about him before he became the coach of PSG? Here's your answer, no one team can succeed if it doesn't have a decent coach. But with Enrique, PSG had a chance.
