This is exactly what happens irl
You are going in with a cold bid and just saying right here I am cash rich and I want that player no matter what, When in real life that hardly ever happens. Take the Ronaldo transfer for example Madrid did not just turn up one day and say here is £80 million, They had to wait over 3 years to get there man dropping hints and unsettling him along the way. They did pay a lot but that’s a lot less than if they had just made the bid and Ronaldo had not pushed it through.
People want FM to be like real life but then want the easy, quick way to make the best team it will not and cannot work like that you need to wait for the full game and have patience when trying to sign people that's what the player comments are in the game for!
It is possible to upset players and make them want to join in the first season but that is unlikely to happen with players such as Messi, Villa and the likes as they are happy where they are and will not just drop everything and move because a new manager has made a bid.
The club and player both need to be unsettled and this takes time!!
