Thomas Tuchel said he addressed video footage of PSG players celebrating Mauro Icardi, Edinson Cavani, and Angel Di Maria\'s birthdays this week.
The images, circulated on social media, were filmed following their 2-1 loss to Borussia Dortmund in the Champions League.
\"I was really surprised by the video on Friday -- really surprised,\" said Tuchel.
\"We have spoken about it internally. I prefer not to talk about it -- that will stay private, between us. \"However, yes, it has been discussed. It must stay internal, though. We are unhappy with these party images.\"
Defender Marquinhos agreed that it was a mistake to upload the footage.
\"We were filmed, there was no malicious intent, and the images were shared,\" said the Brazilian. \"It was a mistake, which we all agree, and we are aware of it.
\"We must take care as there are people who live for this club, travel for miles to support us, and then are sad when we lose.
