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.
I agree with you but I don't think it should be five ordinary/average players as they have always done rather they need to sign more than five top players for different positions if they really want to at least improve for next season because I don't think it will be easy for them to be back to top form instantly. Players leaving will give space for new ones but they still have to follow the ways of Chelsea and release some players not needed anymore, any player not capable of giving 100% performance should be sold too to create room for good quality players.
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.
This past season was very bad for them, they were not far from the relegation zone which is very terrible for a team like Manchester United and if care is not taken they may end up being relegated so they need to act fast. It really a slap on them. They should strengthen their defense and sign a top striker to begin with only then can they compete properly as hold days with the help of the coach.
