i don't know why seems in this transfer window all the players prices are getting crazy and several players have very expensive prices however for Messi or Ronaldo the value maybe above 150 millions
The world is changing and now every team could get their hands on as much money as they would have so it is kinda understandable for me. IF they got the funds and they need those player badly then it is normal for them to be signing that player with huge amount, this is to convinve the player that they are serious as well
