Leicester City's Daniel Amartey has been accused of disrespecting Chelsea following the Foxes' FA Cup Final success at Wembley.
Youri Tielemans' wonder goal settled the contest as Leicester won the competition for the first time in their history.
But as the players celebrated in the dressing room a video has surfaced of Amartey throwing away Chelsea's pennant.
He was filmed holding it up before throwing it over his left shoulder.
The two team captains, Cesar Azpilicueta and Kasper Schmeichel, had exchanged pennants before the final kicked off.
As the video was shared on social media Chelsea fans reacted with anger, with one saying it was "beyond disrespectful and needless" and another calling for the club to "apologise".
And it will certainly add a certain spice to the two team's next encounter, which comes as soon as Tuesday in a crucial match in the race for a Champions League qualification spot.
Blues boss Thomas Tuchel admitted after the defeat that he was disappointed to come up short at Wembley.
He was the first German manager to make the showpiece event but bemoaned the little details that didn't go their way.
"We are disappointed and not angry with our performance from the boys," he said.
"I think the performance is enough to win it. I think today we were unlucky and we’ve never hidden that we need to have that to win at this level. You need momentum, decision making, little details, the referee.
"I think we defended well, counter-pressed well, didn’t allow counter-attacks by one of the best counter-attacking sides in Europe.
"Our decision making in the first half was too hectic, we tried to force the solution. We created two against two and three against three situations that were more promising than we made of it."
Leicester's win means Brendan Rodgers became the first man since Sir Alex Ferguson to win the FA Cup and the Scottish Cup.
Their historic moment comes less than three years after their former owner, Vichai Srivaddhanaprabha, tragically died and Rodgers paid tribute to his son and their family.
He said: “I’m very proud. It’s a historic day for the club. Winning the FA Cup for the first time is clearly a special day.
"I’m so happy for the players and Khun Top [the owner's nickname] and their family, it’s been a dream of theirs to win the FA Cup and we’ve delivered on that. It was an amazing goal by Youri and well deserved."
