Transfers in football are far from simple. There are so many elements that need to be agreed on before we finally see the relevant player wearing their new club's colours.
First of all, the interested club needs to try and find out whether the possible sellers are even interested in allowing the player to leave. Then the clubs will try to come up with a fee both believe is fair for said player.
Of course, there's also the small matter of if the player wants to move to the club and start a new life somewhere else. These are just a few of the elements that need to be considered in a modern day football transfer. It's complicated.
