Newly-released changing room footage of the French Davis Cup team has shown how they fired up for yesterday's final against Belgium - by doing a "haka".
The cringe-worthy rally was led by world No.15 Jo-Wilfred Tsonga, who gestured to teammates while doing numerous gestures from the traditional Maori war dance - or their interpretation of it.
It appeared to work though, as France went on to beat Belgium 3-2 yesterday to claim their 10th Davis Cup title.
Lucas Pouille crushed Steve Darcis 6-3, 6-1, 6-0 to give the hosts a 3-2 victory.
Tsonga had already won his singles match on Saturday NZT.
The last time France won the Davis Cup was in 2001 against Australia.
"Maybe this has galvanised them, hearing each other's stories and knowing they are not alone," say the nurses behind the Facebook group, New Zealand, please hear our voice.
