It is understandable that it is good to buy players that are ready to play for the badge, to give in their all for the club, but I also think it is inherent on the club to go for players that are above average, in the last two or three seasons Manchester United have been going to the transfer window and getting less than average players and yet they want to transform those average players to Superstars, when last did Manchester United get a player in the ranks of Erling Haaland, victor osimhen and rest of those good guys we know that can create impact on their own, just the way we use to have the likes of Ruud van Nistelrooy, Cristiano Ronaldo, Wayne Rooney. The point I'm trying to make is that, Manchester United should go for good players, they have the resource.
The thing is, these superstars will not go to Manchester United. Imagine asking players like Mbappe, Haaland, Yamal, Wirtz, etc, to go to Manchester United. Whoever gives them such advice doesn't like them. The club is in shambles, and going there only means one thing for your career. Look at B. Fenandes, if he were in a club like Bayern, Barcelona, Madrid or even Liverpool, he would be named among the elite, but at United, you have United legends calling him out, saying how he's not doing enough for the team as the captain.
Even the players who were very good in their former teams, got to United and turned trash, for example, Sancho. He was one of the best players in the Bundesliga at Dortmund.
Manchester United needs to find out what it is that makes players and coaches turn average in their club. They should start from there. Then they can focus on signing good player that are not elite, but can make them competitive and put them in the top 6, before they can talk about signing elite players.
