Barcelona president Joan Laporta concedes Ousmane Dembele's future is on the line.
Barca are in new contract talks with Dembele, who's current deal carries a 50m buyout clause.
Laporta said: "Dembl is a player who is very loved by the coach, the technical office and by me. I'm a big fan.
"He has some representatives who are difficult when it comes to negotiating. Respecting his position but they are last minute.
"Now we are in negotiations so that he'll continue and we hope that it will be resolved but I am of the opinion that it will be until the end."
