Former Crystal Palace star Michael Olise has faced criticism for his behaviour at Bayern Munich's Bundesliga title party.
Olise, 23, moved to Bayern from Palace for £50.8million last summer and he shone during his first season, scoring 12 goals and adding 18 assists in 34 games as Vincent Kompany's side regained the German title.
The German giants celebrated their triumph with fans on Sunday in the centre of Munich where they were seen parading the trophy from the balcony of the Town Hall.
Olise is known for being reserved and not the most conducive to interviews and the 23-year-old's antics amid the festivities have come under scrutiny.
According to BILD podcast 'Bayern Insider', Olise was the source of trouble during the championship party.
BILD reporter Christian Falk said: 'At the staff celebration at Munich's Zenith event hall, each player was introduced individually.
'The staff must have been a bit taken aback by the fact that Olise came onto the stage wearing a hood and quickly slipped back into the background, I'm almost tempted to say.
'I understand that he wants to show a bit of coolness, but that's really not very polite.'
Falk's comments come after a video also circulated of Olise playing chess on his phone during the middle of Bayern's celebrations.
In a clip shared by team-mate Sacha Boey, Olise could be seen playing the game, before he asked Kingsley Coman for advice on his next move, leaving Boey and Alphonso Davies in hysterics.
Another BILD reporter Tobias Altschaffl added: 'He's a stubborn guy. Off the pitch, he doesn't interact much with strangers. That's not exactly appropriate, and it's a bit disrespectful to the fans.'
Meanwhile, during Olise's unveiling at Bayern, he answered questions almost exclusively with yes and no, while he is known to rarely stop in the mixed zone after matches.
He has also conducted several interviews in the past where he is clearly shy when speaking to the media.
In fact, during his time at Palace, one post-match clip after Olise scored an injury time winner against West Ham in 2022 went viral.
'Just talk us through it', Olise was asked in relation to his 96th minute strike.
'Through what, the goal?' he replied awkwardly, to which the interviewer confirmed.
'I think Wilf passed me the ball, shot, scored', he replied.
'Nice and brief!' joked the interviewer in response. 'But it was a moment that won the game, what is the feeling like when the ball hits the back of the net?'
'It's a good feeling', Olise replied bluntly again.
'Do you feel you deserved it overall?' he was finally asked.
'Yeah', was the response.
