Sometimes it's not about just spending money for hiring expensive players for the team, even if you have the most expensive players you should know how to manage these players and which expensive player you should buy, just pending money and hiring the most expensive player in the world won't help any team in a great match they have, I think they have to consider using another coach and then the need to hire the players they really need not any player with expensive price.
To see the quality of a coach, you really don't have to have expensive players, because no matter how expensive and how good the players are, if the coach can't understand the person he is training, they will not be able to maximize their abilities. Many good players have had to decline when they were coached by coaches who couldn't understand what they wanted. I really understand that players must understand the instructions of a coach, but on the other hand the coach must also understand the character of a player. The coach has 11 players on the field with different characters and playing styles. It is the job of a coach to be able to get them in the same rhythm with their respective playing styles.
