Forward Moussa Dembele has taken to social media to suggest that he is unhappy with being denied a move away from Celtic.
Both Marseille and Lyon have been keen on signing Dembele before the end of the transfer window, and manager Brendan Rodgers has previously acknowledged that discussions were taking place.
However, Rodgers said on Thursday night that he expected the Frenchman to remain at the club, and that seemingly prompted Dembele to post two messages on Twitter.
According to Sky Sports News, Dembele was directing the tweets at Rodgers, who had commented on the player's future after Celtic had qualified for the group stages of the Europa League.
The 22-year-old had been left out of the squad for the game in Glasgow.
