Cokanasiga will start on the wing against French Top 14 side Lyon on Friday night (20:00 BST) as Premiership leaders Bath look to clinch their second trophy of the season in the European Challenge Cup final, having also been part of the squad that won the Premiership Rugby Cup in February.
He scored a scintillating try last weekend as they thrashed Leicester 43-15 in the league, running from deep in his own half after Max Ojomoh’s interception.
Bath head of rugby Johann van Graan said Cokanasiga has become a “more rounded player” during his tenure at the club.
“He’s by far the biggest winger that I’ve coached but Joe’s got this amazing ability to finish tries, he’s got this hunger to get better,” he said.
“We’ve ID’d certain bits of his game he needs to get better and he’s become a much more all-round player.”
Cokanasiga agreed his consistency across the pitch has come with the more experienced he has become.
“As I’ve gotten older my priorities have changed of how I need to perform in the game,” he said.
“Then we’ve got people like [Bath attack coach] Lee Blackett that has a different view of the game than I do and that’s helped me improve massively.
“Johann’s someone I can go and speak to about anything and let everything out, he can be honest with me, I can be honest with him, same with Lee and JP [Ferreira, defence coach].
“They give you a lot of confidence and that’s massive in players.”
