Nantes coach Vahid Halilhodzic is demanding club owner Waldemar Kita keep hold of Emiliano Sala.
Kita is locked in talks with Cardiff City about a fee for the striker - a move which Halihodzic is unhappy about.
The coach said, "If I'm not happy, I know what I'll have to do, do not worry.
"We must understand why the president wants to sell a player while the club is in deficit. But who will assume if the club goes down in Ligue 2? There can be many things happening.
"Football is a liar in poker."
