Matthew Dellavedova's future is yet to be officially confirmed, but Cleveland Cavaliers team-mate LeBron James has suggested it lies elsewhere.

James tweeted a congratulatory message to Dellavedova after reports emerged the Australian is set to move to the Milwaukee Bucks.

"Congrats to my brother! @matthewdelly on his deal! Good luck in Milwaukee! Very deserving to you and your family," he tweeted.

The Cavs point guard has reportedly signed an offer sheet from the Bucks for a deal worth $38million over four years.

If reports are correct, Cleveland have three days to match their offer starting July 10.

Dellavedova has spent all three of his NBA season at the Cavs, helping them to back-to-back Finals and a championship last month.
