They've already enticed one All Black up State Highway 1, can the Blues repeat the feat and lure Liam Messam away from the Chiefs?
This week's signing of Sonny Bill Williams was the first real statement of intent that Tana Umaga's team can now attract the highest calibre of player and Messam, off contract this year, certainly fits that bill.
The Rugby World Cup winner and two-time Super Rugby champion is 32 but believes he still has "a few good years left" in New Zealand rugby, having been reinvigorated while spending this season in the sevens set-up.
Once those commitments come to an end, Messam will be looking for his next challenge. And while tempting the loose forward away from the Chiefs will be difficult, Messam is impressed with what he's seen on the other side of the Bombays.
"They're building a great environment and culture up there and I've only heard great things about what Tana has done," Messam told Tony Veitch on Newstalk ZB. "He's a great man and has great respect just with his name."
