Fijian flyer Waisea Nayacalevu scored two tries against Seremaia Bai's Castres to help his Stade FranÃ§ais lead the France Top 14 competition.
The former national 7s and 15s rep relegated former Wallabies flyer Digby Iowane to the bench and stamped his mark in his team's number 14 jumper as they convincingly won 32-6 on Friday.
Nayacalevu's tries helped the team to claim the number one spot in the Top 14 competition — two points ahead of Sitiveni Sivivatu's Clermont team who are yet to play against Jo Rokocoko's Bayonne team this weekend.
The Serua native was unstoppable on the flanks using his speed and power to bulldoze his way to the tryline.
Meanwhile, this weekend's competition will see the battle among Fijian players in their respective Top 14 teams.
And the highlight of this week's competition is the inclusion of Flying Fijians skipper Akapusi Qera alongside Fijian speed merchant Timoci Matanavou for Tolouse against Jone Qovu's Racing Metro.
Qera who spent the past seven years with English powerhouse Gloucester will start from the bench likewise for his Racing Metro opponent and former teammate Qovu.
Another interesting encounter will see the battle among five Fijians. Former All Black flyer Jo Rokocoko will form the inside backs combination with former flying Fijian centre Gabrieli Lovobalavu against Clermont.
Clermont will have French Fijian winger Noa Naikataci.
Naikataci will partner former All Black speed merchant Sitiveni Sivivatu.
