Crusaders fullback David Havili has received the biggest endorsement of his career, after former All Black Mils Muliaina said he should be in the All Blacks squad for the British and Irish Lions tour.

Leading from the back, Havili has played a massive role for the Crusaders, who remain unbeaten this year.

Speaking to RadioLIVE's Sunday Sport, Muliaina said he would take the 22-year-old over Hurricanes prospect Jordie Barrett, because of his positional play.

"Going off form you'd have to pick David Havili," said Muliaina.

"He has great positional play, he can kick, he can counter and he can stay on his feet so the forwards to get over him and get the ball back."

Despite players like established All Blacks Ben Smith and Israel Dagg missing valuable time due to injuries, Muliaina believes they should be included in the 33-man squad due to their experience.
