The Toronto Raptors sent "nothing but good wishes" to Kawhi Leonard and Danny Green after they agreed moves away from the NBA champions in free agency.

Both stars played key roles in the Raptors' 2018-19 success, with Leonard the NBA Finals MVP, but the two will move on ahead of next season.

Leonard is set to sign a deal with the Los Angeles Clippers, while Green is going to the same city with the Lakers.

The Raptors acknowledged the two big departures in a series of Twitter posts on Saturday, including a statement from president Masai Ujiri.

"We are very thankful for the year Kawhi and Danny played with us here in Toronto," he wrote. "And I know the city and the entire country of Canada are grateful for everything they did to help us win our first NBA Championship.

"On behalf of the Raptors, I say a very heartfelt thank you to Kawhi and to Danny, and we send them and their families nothing but good wishes.

"As an organisation, the Raptors will focus on the future and continue our pursuit of a second championship."

Leonard is yet to discuss his move, but Green posted a video message on social media.

"I had a fun time in the city of Toronto, love the organisation," he said. "Thank you, guys. Thank you to my team-mates. Thank you to the fans. Always have a great place in my heart. Never forget obviously the historic run we had."
