Paris Saint-Germain were defeated by Borussia Dortmund in the first leg of the Champions League Round of 16.
The defeat did not prevent Icardi, Cavani and Di Maria from celebrating their birthdays in style just 48 hours later.
Edinson Cavani and Angel Di Maria share the same birthday, February 14, and Mauro Icardi’s birthday is just a few days later on the 19th.
What started out as a quiet evening with cakes and children in a Paris hotel, turned into a festival of shirtless players. Neymar showed off a belly and that's very unusual for a player of his rang.
The PSG players have been heavily criticised on social media.
Thomas Tuchel talked about it saying: "I was really surprised yesterday afternoon when watching the video."
"You can be sure that we talked internally. I don't want to talk about it now, but we talked about it within the club and it has to stay that way."
He added: "You can be sure that we are not happy with this image. We talked together as a team and it is now an internal matter.
"I am here to improve my group. I cannot give advice to the club, that is not my role."
