Stade Français moved to the top of the Top 14 standings after registering a 38-3 victory over Biarritz in Paris on Friday.
The home side marked their return to the refurbished Jean Bouin Stadium with a dominant display in front of their partisan supporters.
After three years of playing their home fixtures across the city at the Charlety Stadium, tries from Pierre Rabadan, Julien Arias, Jonathan Danty and Waisea Vuidravuwalu propelled Stade to a commanding win in their home opener.
A pair of penalties from Stade scrum-half Julien Dupuy put the hosts into an early 6-0 lead before Biarritz fly-half Julien Peyrelongue reduced the arrears with a penalty of his own.
Stade duo Antoine Burban and Pascal Pape both then saw tries ruled out upon video review before long-serving back-row forward Rabadan powered over on 22 minutes, this time his effort upheld following replays as Dupuy converted to extend the home side's advantage.
A drop-goal from Jules Plisson before the interval moved Stade 16-3 ahead before they turned on the style in the second half as Biarritz were reduced to 13 men in a matter of minutes with Daniel Waenga and Arnaud Heguy both sin-binned.
Replacement scrum-half Jerome Fillol knocked over a penalty with Arias then touching down as the hosts capitalised on their two-man advantage before the introduction of debutant South African fly-half Morne Steyn on 61 minutes further galvanised the home side
A converted Danty try moments after the Springbok's arrival was soon followed by a try from Fijian winger Vuidravuwalu, with Steyn adding the conversion to cap off a resounding success that sent the capital club three points clear of Toulon ahead of Saturday's action.
