Liverpool's France striker Djibril Cisse warned Rafael Benitez that he would leave the Premiership side if he did not get more first team action.
"When I'm lucky enough to start (with Liverpool) it's as a right winger. It's not my position but I do it for the team. If things don't sort themselves out by December I think I'll leave," said Cisse ahead of Saturday's World Cup qualifier against Switzerland.
Cisse, 24, said that he was still considering joining Marseille in France, but would also like a move to Spain.
"I'd also like to go to Spain, but I think what I really want to do is leave Liverpool," he said Thursday.
"I'd be disappointed to leave Liverpool, I was beginning to adapt but I have to think about my career as well.
"Six months before the World Cup I can't be playing just one out of two or every three matches. It's a bit selfish, but I have to play."
But Cisse said that he has not discussed the situation with Benitez.
"I will not go and demand talks," Cisse said. "That's not in my character."
Liverpool, meanwhile, were reported Thursday to have offered Real Betis 10 million euros plus Cisse for attacking midfielder Joaquin, sports daily As reported.
Cisse, who recovered from a broken leg to play in Liverpool's astonishing Champions League final triumph in May, has spent most of this season warming the bench after a mooted move to Marseille fell through.
Cisse, who has 23 caps for France and scored seven times for the national side, has not played for Liverpool since September 10.
He joined Liverpool from Auxerre for 14 million pounds (24.7 million dollars) last year.
