Tottenham’s players risked angering boss Mauricio Pochettino after their win over Borussia Dortmund.
Harry Kane scored the only goal of the game in the Champions League last-16 second leg as Spurs ensured a 4-0 aggregate success.
Pochettino’s men are now into the quarter-finals for the first time since 2011 with all eyes on next week’s last-eight draw.
But the Spurs boss might not be happy with the antics of his players – in particular Jan Vertonghen – after the victory in Germany.
The Belgian defender uploaded a selfie from inside the dressing room, alongside Eric Dier, Michel Vorm and Erik Lamela.
Vertonghen appeared to have forgotten a warning from Pochettino about post-match celebrations.
The Argentine hit out at Arsenal’s players after they celebrated in the Emirates dressing room following their 4-2 derby win.
Pochettino even insisted his side wouldn’t be taking part in any dressing room selfies until they had won some silverware.
“Obviously if you win a trophy like I did when I was a player, it is time to celebrate,” he said in December.
“Of course, show the fans you are happy, it’s fantastic — but when you win something special.
“I accept people need it. It is how you feed your ego and I accept it is a new world. But I am of the older generation and, personally, I don’t like them.
“This is my mentality. I accept new technology but I try to keep a bit of that away.
“I love to celebrate the things with your team-mates but I love to celebrate in private and not make it public.”
Spurs boss Pochettino has also been handed a two-match ban following his clash with Mike Dean after the defeat to Burnley .
