2021 tour

Lions coach suggests All Blacks 'decider' for warm-up

Gatland, 56, was in charge as the Lions and the All Blacks drew their three-Test series in New Zealand in 2017.

The former Wales coach says a fourth fixture could help rugby to generate revenue after the coronavirus crisis.

"It's potentially an opportunity to make four or five million pounds," Gatland told Sky Sport.

Ahead of next summer's tour, he raised the prospect of a meeting with the All Blacks as preparation, saying he had already spoken with NZ Rugby chief executive Mark Robinson about a game with the New Zealand Maori.
