Luai revealed he had not yet informed Ciraldo, a former assistant coach at Penrith, of his decision to choose the Tigers over the Bulldogs.
"This is the phone call," Luai said of the press conference he called on Wednesday.
"I've got a lot brothers there (at the Bulldogs) already, and Cam Ciraldo is like my second dad.
"That's why the process has dragged on for quite a while ... that was a tough decision."
No way we get this over the line without Richardson. This shows the Bulldogs were in the mix right up to prior the announcement and it was confirmed by Richardson in the recent interview - he was confident but was never fully sure of which way he would go. A massive turning point - to get the player we wanted ahead of another club.
