Bordeaux boast world-class players such as Matthieu Jalibert, Louis Bielle-Biarrey, Damian Penaud, Maxime Lucu and Yoram Moefana.
A French team has also won the Champions Cup in each of the past five years.
But Bordeaux have not had everything their way this season, especially in the league where they have stuttered and lost 10 of 22 Top 14 games, leaving them sixth – 17 points behind leaders Toulouse.
Bath also have world-class talent of their own – including Scotland fly-half Finn Russell, England centre Ollie Lawrence, Argentina back Santiago Carreras and South Africa prop Thomas du Toit.
And the experience of winning three finals last season – the Premiership, European Challenge Cup and Prem Rugby Cup – has got the monkey off the back in terms of bringing silverware back to a city consumed by its love of rugby.
“Every team has weaknesses – we have weaknesses – but the team that we’re coming up against has more strengths than most,” Obano said.
“They’re a great team but we think we’re a good team. It’s just about going out there and trying to be the best version of ourselves.”
