In 2021 when Ronaldo made back a second return to Manchester United, as it was stated in the interview he made, which part of it was the dilapidation state of team and training facilities. He said things didn't change that it's almost the same way he left things back in 2009 that's how they are. Of course we all know that in that period of time his played for Real Madrid and Juventus and noticed that these teams had upgraded facilities unlike United. It's announced now that the club management has taken that criticism into account and are now upgrading Carrington which is their training ground with around £50 million. That's a whole lot of money and once the upgrade is completed, the difference will surely be noticed.
Ronaldo made this statements when he was having issues with Ten Hag, and many people were blaming Ten Hag for mismanagement because same issue happens to David De Gea that made him leave the club, and now that Ten Hag is not more in charge of the team, Amorim is also finding it difficult to get things right in the team which simply shows that there are management issues from the club owners which I think needs to be fixed properly before the team will be back on track.
However, Amorim and the management are making effort to sign some players, they have succeeded in signing a striker and are also looking forward to sign more, if they can get all the players they are targeting, they can do better this season.
Maybe you actually missed the memo, it wasn't Ten Hang that was bashed instead both Manchester United fans and the board including those who doesn't like Ronaldo bashed him. It was Ronaldo that received insults and hate after he made those statements and not Ten Hang. It was after the interview his contract was terminated, because he revealed a lot of things about the club and it's management. It was only few people who saw the truth in what Ronaldo said that stood by him. It was later Manchester United fans saw Ten Hang for what he truly was before most of them started calling for his sack.
