Honours were even in a recent 26-26 draw in Toulon following Clermont's 24-21 home win earlier in the season.
"We do not put a lot of importance on the first two clashes with Toulon, this final is a separate match altogether," said Azema.
"We are well aware of the wealth of talent Toulon have at all levels - they have dangerous players in all areas.
"They have speed out wide, potency and explosiveness in the centre and half backs who manage the game well
"Their forwards are rich in several hundred international selections and we will have to be vigilant in every corner of the ground.
"We will try to surprise them but we have developed our game throughout season and we are not going to confuse everything while attacking these last few matches."
