-snip- Although Manchester United spent a lot of money, they failed to select the right players for their squad.
Spending a lot of money will not make a team a strong team. A similar thing also happened to Chelsea in the previous few seasons where they made many mistakes in buying players. Chelsea has spent around 319 million pounds sterling to spend on players in the summer of 2023. And as a result, Chelsea only managed to finish in sixth place in the standings at the end of last season. They also failed to reach the UEL after United managed to win the FA Cup. I can say that Chelsea suffered a big loss because the results did not match expectations. So far only Cole Palmer has contributed significantly to the team and is Chelsea's best purchase so far.
A coach needs to know what his squad needs before buying players. Weaknesses of the team should be identified. But Ten Hag has completely failed to identify his squad's weaknesses. And that's why he couldn't stabilize the Manchester United team even in 2 years. Manchester United management provided large funds to Ten Hag for player purchases. Ten Hag invests money in young players. But Manchester United needed an experienced striker. Had the Ten Hag added an experienced striker to his squad, perhaps we would have seen a more organised gameplay from Manchester United last season.
However, not all teams that spend a lot of money to buy players then fail to get good results, such as the failures experienced by Chelsea and Manchester United. Because after all, there are still many other teams that have spent a lot of money and the results have also been successful, perhaps, for example, Liverpool and Manchester City. Therefore, there are two possibilities for a team to succeed or fail after spending a lot of money to buy a lot of new players and also recruiting a new coach.
But indeed, basically the team will be successful because it has a coach and has the right management. Because after all, a great coach is certainly able to make players who were previously mediocre into successful players with good quality and performance. Although indeed, having quality players will make it easier for the coach to work to make the team perform well. So yes, in this case ofcourse all lines play an important role in actually getting success and trophies.
