A player who has been at a club for a certain time, who is a certain age and who is in the latter stages of his contract is legally entitled to buy out the final year/s of his contract for the salary owed.
Messi ticks every box, we can basically buy out the final year of his contract. Talk of 150m is nonsense from a basic legal standpoint.
We might toss them Garcia and Angelino as a bone to ease the deal but Jesus is worth coniderably more than the final year of Leo’s wages so that sounds like bullshit
