Manchester United team is supposed to sign more than five good players if they what to be back to good form again, the players that are living after the summer are giving more rooms for the club to bring in good players so if the management wants the team to ever make it to the top4 again they have no reason not to spend huge amount of money on the transfer market to ensure they get quality players in the team.
They actually need to sign more players because it has not been easy for them. For some time now, Manchester United has been struggling, and for some time now, they have needed to be very active in the transfer window. And Manchester United needs to improve because it is becoming a slap in their face, so this is enough reason why they need more players, because they have failed their fans, and they need to. And Manchester United used to be one of the most admired because even when Ronaldo returned to the club, he was disappointed at what he found.
Manchester United's problem is not the number of players they sign (or that they need to sign), because they always buy a lot of players but those players are often overpaid and there is no logic behind. They bought Højlund, they paid like 70-80 million euros for a player who was not even a regular in Atalanta's line up and scored just a few goals, why would you do that? And why would you get Casemiro at the end of his carrier, giving a bunch of money to Real Madrid? Again, they are just buying random players without any plan behind.
