Filip Helander admits he has been taking "little jibes" at former Celtic star Mikael Lustig after Rangers title win.
The pair are on international duty with Sweden as they kick-off their World Cup qualification bid.
However, attention turned to Helander 's success when chatting with team-mate Lustig after prying the Premiership title away from their Glasgow rivals.
Lustig, who is currently playing for AIK in his homeland, became a fan favourite at Celtic Park as he helped the team to eight league titles in a row.
The cheeky defender famously stole a policeman's hat while celebrating a goal against Rangers, much to the delight of the Celtic support.
Helander admits he couldn't resist bringing up the end of Celtic' s domestic dominance with the cult hero.
The Ibrox centre-back told Swedish outlet Fotbollskanalen : “He’s not so happy but I’m happy. He has received little jibes.
"But he has actually congratulated me, in fact. I expected nothing else."
The former rivals could line-up at the back for their country in the World Cup qualifier triple header against Georgia, Kosovo and Estonia.
