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.
The whole Manchester United team thought they had just one problem mainly the coach but, it seems the players also need to improve in terms of their performance. Honestly, during their past performance with Ronaldo they had zero effort I guess Ronaldo had to leave for his own good. Signing a new player is valid although there’s a difference when it comes to going for top players which requires a lot, personally they should go for quality not quantity possibly they can build a nice team.
