Melbourne United have officially re-signed Dave Barlow, while NBA import Shawn Long looks poised to join the club.

Last season's NBL runners-up formally announced the 35-year old power forward was back for the 2019-2020 season after a stellar campaign when promoted to the starting role.

Long posted a tweet on Sunday stating he has signed with Melbourne for next season, but the club has not yet formally announced the move, meaning his contract must still be in the process of being approved by the league.

If Long does join Melbourne as expected, it will give the team two of last season's best imports, although it also means title-winning centre Josh Boone won't be returning despite three seasons of excellent service.
