I have a perfect formula for signing messi:
You need to have enough money to get your bid accepted(145mil in my case). After they accept it, you offer contract to messi,he will refuse it. Do this 3-4 times and he will sign for you here is what it says on messi's profile after he signed contract for my team:
I quote:
''Concerned at the club's willingness to listen to offers for him''
