If Manchester United wants to take the team to a better performance, Ten Haag must change. Because he is well known as the manager of Manchester United team for a long time, but the tactics he used are at least weak nowadays. No matter how well the players perform on the field, if the manager does not control his strategy properly, it will not be possible to win the game.
Managers' strategies are of great use, as they play the biggest role in winning. That is why the performance of the Manchester United team in the current position is very weak only because of the coach, if the coach is changed, the Manchester United team will perform better than before.
Giving a thought about the whole dimension of the team. Erik Ten Hag have to change the game tactics of the team because giving room for improvement would do a whole of great work for the team. Winning is based on the mindset, the Red Devils really need to bounced back to winning ways because that's the only thing that would put them back on track especially in the English Premier League this season. Watching the poor unstable performance of Manchester United in EPL games, not encouraging from their ends.
Manchester United's match strategy is not right. Ten Hag probably changes his match strategy almost every match. Since the bonding between Manchester United's players is weak, Ten Hag cannot stabilize Manchester United's performance even by changing match tactics. Ten Hag must first develop a friendly relationship with Manchester United's players. And the internal problems of the squad have to be found. If ten Hag can find problems within the squad, maybe he can solve them. However, given the strange performances we have seen from Manchester United in the first few matches, this team will not be able to qualify for the Champions League.
