The striker has been linked with a move away from Crystal Palace this month, with the French side interested in signing him.Speaking in his pre-match press conference, Vieira has been questioned about the Frenchman, yet he decided to keep quiet.
Meanhwile, Saint Etienne coach Pascal Dupraz has revealed that he has been having regular phone calls with the forward.
"Not that I am aware of," was Vieira's response.
"He is a Palace player and he has been training really well all week. He will be part of the group for the game tomorrow."
"The more we talk about this player, the less he will come to AS Saint-Étienne, but what I can tell you It's that we have him on the phone regularly," the 59-year-old told France Bleu. "There are rules to be observed and it is still inappropriate to say that he will join us but there is a will (to make him come) and it is unanimous."
