Joey Barton has warned Newcastle his future at St James' Park rests on the club matching his own ambition.
The 28-year-old was reportedly ready to commit to the club on a new deal in January before Tyneside was rocked as striker Andy Carroll was sold to Liverpool for £35million.
Both Barton and the club have repeatedly talked of negotiating a fresh contract since, but they are currently in dispute over the length of the potential deal.
The former Manchester City man, who has been a key performer for Newcastle this season, insists he will only stay with the Magpies if he feels the club are making progress.
In an interview with French magazine So Foot, he said: "It's important to respect the people who come to the stadium or watch the games on telly.
"That's what I told [the Newcastle management]. I told them the goal shouldn't be just to survive, to finish 16th or 17th, every season.
"We had a good player, Carroll, and we sold him. I told the management that I was worried, that I was scared this might happen every year. But they assured me they don't want to go down that road.
"I don't know if I believe them. I told them I might stay this summer because we have some good players and money to spend. But I'm going to wait and see if players like Kevin Nolan, Cheick Tiote and Jose Enrique stay.
"If Nolan signs a new deal, I will as well. But I hope the club step things up. I want to be ambitious and I think the club share that desire."
