French sports daily L'Equipe reported on Tuesday that Qatari-owned PSG had suspended Messi for two weeks and decided against exercising an option to renew his contract for a third season after he made an unauthorised trip to Saudi Arabia.
Messi is a Saudi ambassador for tourism and his longtime rival, Cristiano Ronaldo, signed for Saudi club Al-Nassr in December in a deal reported to be worth around $220 million per year.
Messi's trip to Saudi Arabia resulted in him being suspended without pay and banned from training with his team mates by PSG, L'Equipe said.
Saudi Minister of Tourism Ahmed Al Khateeb confirmed Messi's trip to the Kingdom.
"I am happy to welcome Saudi Tourism Ambassador Lionel Messi and his family on his second vacation in Saudi," Al Khateeb wrote on his Twitter account.
