Torino president Urbano Cairo is upset with Nicolas Nkoulou over an interview with L'Equipe.
The defender has stated he'd play again for Toro, but also suggested they had gone back on their word of selling him.
“He arrived two years ago, I agreed to take him on loan with an option to buy," Cairo said at Simone Verdi's official unveiling.
“When the season ended, his agent told me he could go to Sevilla: I replied that I wanted to keep him with us.
“I didn't know about any promises he made with the sporting director. I was the only who took up the option to buy him.
“I admitted I'd listen to offers for him the following summer, but they had to be opportunities that we considered appropriate.
“I'm also not going to strengthen our rivals. The issue will be resolved via the appropriate chanels, not through interviews with L'Equipe.
“Hearing that his head wasn't there for a crucial game [Europa League playoff second leg against Wolves] hurt us a lot.
“We've explained what needs to be done. It's something we already know."
