Firebrand Turkish goalkeeper Volkan Demirel was at the centre of a new scandal Tuesday after jumping onto a rival's back in an Istanbul derby game and then likening his opponents to stray dogs.
Demirel was playing with his side Fenerbahce against their great Istanbul rivals Galatasaray in the Turkish Super Cup, the traditional curtain-raising event for the season that starts later this week.
A typically tense and fractious game late Monday ended with 10 yellow cards but no goals after extra time and the match went to penalties.
Galatasaray's Brazilian international Felipe Melo stepped up to take the third penalty but skied his strike metres over the crossbar.
But in an extraordinary move that has now gone viral on social media, Demirel inexplicably then ran up to the retreating Melo, charged into him and jumped onto his back.
Once back on the ground, he then began remonstrating with the Brazilian and the referees had to intervene to stop a full fight ensuing.
But Demirel -- whose first name means "volcano" in Turkish -- lived up to his name and did not leave things there.
In a post-match television interview, Demirel appeared to compare his opponents to the stray dogs who populate the streets of Istanbul.
"Either the municipality poisons the unwanted stray dogs or I will do it," he said.
Turkish media said he now risks a hefty ban for his actions ranging from one to three games for the jump and two to six for the dog comments.
He could also be the subject of a legal probe, NTV television reported.
Demirel, whose fiery temper has got him into trouble in the past, was Tuesday however unrepentant, saying his comments had been misinterpreted.
"I'm a person who knows what to say and how to say it," he wrote on his Instagram account.
"Those trying to teach me good manners should first look at what they have written," he added.
He could at least celebrate helping his side win the game, which Fenerbahce won 3-2 on penalties.
