It could be around 40 million euros
Leo Messi hasn't signed his contract extension with FC Barcelona yet. However, after his celebrations of the 6-1 against PSG, it certainly look like he wants to stay at the club. And the club will do everything in their hands to secure that the Argentinian continues in Barcelona.
This weekend Mundo Deportivo reports that Messi's contract extension is going to be really expensive. It won't only be paying Leo Messi the highest salary every seen for a football player. He will also receive a signing on fee around 40 million euros.
Last year the club announced that 63 million euros had been paid to secure the contract extensions of Neymar, Busquets and Mascherano.
