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.
because of the many changes that occurred at Manchester United, this is Ronaldo and his contract was terminated, maybe there was a lack of compatibility at that time, and that was indeed a reason that made his fans feel disappointed because they had not been able to win the Premier League trophy that they dreamed of, of course, the glory can certainly be repeated depending on the recruitment of quality players, of course, and it takes quite a long time to wait for it to come back.
There is something you quite need to understand here, Ronaldo at that time was feeling like Ronaldo of his prime while on the performance side, he is just an average player that is about to log off the football career and rest and he wasn't giving what ETH wanted at that particular time plus the PR was getting on his nerve and he became frustrated especially when it became annoying that people were using his family loss to talk things they want at him and he became fed up and was like, fu$k it, I'm leaving.
Was he right or wrong? Definitely he, he was right about the state of the club, everything has change about the management and he wasn't the only person that spoke about it, Rashford experienced similar challengs that's why he happily left the club and till now, there is nothing good that has happened to the team since he left and by the way, leaving Manchester United was the best thing that happened to him, he is playing fot the money and not any trophy again.
