Mbaye Niang has said he is sorry if he "hurt anyone" after retweeting a message that insulted AC Milan coach Massimiliano Allegri.
After making just one Serie A start this season, Niang, 19, joined Montpellier on loan last week and scored on his debut for the Ligue 1 club in their 2-0 Coupe de France win over amateur outfit Rodez on Sunday.
Shortly after the final whistle, he retweeted a number of messages of congratulation from some of his 219,000 followers, including one in which Allegri was blamed for the teenager's failure to establish himself in Italy and branded an "fdp" -- French shorthand for "fils de pute" ("son of a bitch").
"When did I insult Allegri? I didn't. So don't take it to mean anything. I retweeted without paying attention," Niang tweeted on Sunday evening after he had deleted the comment.
"I retweeted a tweet that should never have been. I deleted it as soon as I realised. I never wanted to lack respect and even less so to people who have put their trust in me. I apologise if I have hurt someone. Now, stop with these useless polemics."
J'ai retweeté un tweet qui n'aurait jamais du l'etre. Je l'ai effacé dès que je m'en suis rendu-compte jai jamais voulu manquer de respect— Mbaye Niang (@OfficialNiang) January 5, 2014
