All Black halfback Augustine Pulu has already left the Chiefs to join the Blues but there could be more big signings as Tana Umaga looks to bolster his squad for 2017.
Sonny Bill Williams and Umaga are close and the Blues have signalled they are keen to capture his signature following this year's Olympics Sevens in Rio.
Rene Ranger said SBW knows Umaga very well and he guesses the Blues would welcome him with open arms.
