'I'm smashing my TV': Former All Black unhappy with Crusaders coach Robertson

Springboks Director of Rugby Rassie Erasmus also took to Twitter to praise Robertson's effort, sharing adulation for the way that the Crusaders coach expresses himself after success.

In his post-match press conference, Robertson said he was 'extremely proud' of his Crusaders side who replicated the feats of the 1998 side by beating the Blues at a 'special' Eden Park in the final.

"Extremely proud. Through the week we dug pretty deep into what it takes to win a championship and reflected on a lot of the other teams that had done it and why," he said.

"That connected us probably into how hard it was going to be. There was a lot of messages from (past) players, coaches and captains that just reflected that probably first 50 minutes.

"It is special to win at the Garden. We talked about it. It's very hard for any team to win here, - any team playing the All Blacks or the Blues.

"It's a pretty special place and we had to go to a higher level if we wanted to [get the win] and step up, and we did that."

Of the five titles the Crusaders had won under Robertson previously, just one had been won away from home against the Lions in Johannesberg.

Whilst their sixth title at Eden Park was special, it couldn't be compared to their victory at Ellis Park due to the differing circumstances.

"Yeah we've done it a few times [winning the competition] but Ellis Park... Take nothing away from this but I think because it was the first, it was unique," he said of the team's 2017 championship.

"That was pretty special. You were away from home. There's a few more, where the air is thin and you've got a lot of different elements.

"But just this group and led by some great men and a great captain."
