Messi skipped PSG training on Monday to travel to Saudi Arabia to fulfill sponsorship obligations with the Saudi Arabian Tourist Board, which he did without permission from the club.
PSG fans then gathered outside the stadium to sing derogatory songs about Messi. Messi was also sanctioned by the club, who suspended him from all activities for two weeks without pay.
Messi posted a video explaining the situation and apologizing on Friday evening.
In his words, "I thought we were going to have a day off after the game as always. I had this trip organized and I couldn't cancel it. I had already canceled it before…?.
"I apologize to my teammates and I'm waiting for what the club wants to do with me".
