There has been "no progress" made between Klay Thompson and the Golden State Warriors over a contract extension, according to Adrian Wojnarowski.

"I'm told that there been absolutely no progress on a Klay Thompson extension in Golden State, that they are both still apart on years and money. 

"And there's a very real possibility that Klay Thompson goes into free agency next summer without a deal," said Wojnarowski on NBA Countdown.

Thompson is entering the final year of a five-year, $189.9 million deal and will have a base salary of $43.2 million this season.

Bob Myers, the former president of basketball operations for the Warriors, acknowledged the difficulty of the negotiation.

"This is a delicate negotiation. From what I know and see, he wants to stay. They want him to stay," added Myers.
