Nantes president Waldemar Kita believes that Filip Djordjevic has not agreed to move to another club next summer.
The 26-year-old Serbia international striker has been linked with a number of Premier League clubs in recent weeks.
"I've made contract offers to him for the last month and it's down to him to respond," Ligue1.com quotes Kita as saying. "It's impossible that he's already reached an agreement with another club as he would have told me about it.
"If he uses logical reasoning, then he'll sign for us without hesitating. I've always protected Filip and if it wasn't for me, he would have left a long time ago.
"Filip needs to reflect well. He's the captain and star at one of the best teams in France. How would he cope with not being the star elsewhere? I know his personality well."
Djordjevic joined Nantes from Red Star Belgrade in 2008.
