Lille have appealed for calm after a fight broke out at the city's airport following the arrival of Florian Thauvin with the Marseille squad on Monday.
Thauvin, 20, refused to train with the Lille squad after finally completing his move from Bastia last summer in an attempt to force a transfer to Marseille. The France under-21 international, who had initially signed for Lille last January when Rudi Garcia was still coach and before the club missed out on European football, eventually got his wish in the closing hours of the summer transfer window.
After landing in Lille ahead of Tuesday's Ligue 1 encounter at the Stade Pierre Mauroy, Thauvin was insulted by a vociferous group of Lille fans who were confronted -- according to French media reports -- by two members of the Marseille staff. One person was arrested as a result of the incidents.
"The Lille board calls for calm and asks their supporters not to show an excess of pointless aggression towards our opponents but rather show -- more than ever -- their support for their team," a statement on Lille's website read.
Lille chairman Michel Seydoux, who publicly criticised Thauvin's attitude last summer before making a significant profit on the player he bought from Bastia for 3.5 million euros, told RMC he no longer bears a grudge.
"The page has been turned. There was a lively and original story, but now it's over. Everyone's in his place. I think Baup is happy, we're not unhappy. And we're content that Florian is working well at Marseille."
