Stade make light work of Treviso
A Parisian onslaught in the first 11 minutes saw Waisea Vuidravuwalu, Julien Arias and Paul Williams cross to put the French side in the driving seat.
The bonus-point was wrapped up soon after through Sylvain Nicolas, before captain Sergio Parisse and a second try from Williams wrapped-up the rout.
The Top 14 champions have lift-off in this season's Champions Cup after defeat to Leicester Tigers in Round One.
Stade wasted no time in silencing the Stadio Comunale di Mongo crowd.
The Parisians snatched an early lead with a penalty from Jules Plisson, before breaching the Italian defence. The ball was worked out wide to Vuidravuwalu, and there was no stopping the Fiji international.
And it was to get even better for the visitors when Vuidravuwalu's wing colleague Arias got in on the scoring act. Plisson was on target again to secure a 17-0 lead after eight minutes.
Stade's free flowing game was at the fore. Centre Williams was the next man to go over, as the French side blitzed Treviso in the first 11 minutes to claim a 22-0 lead.
And they were not ready to slow down the scoring. Flank Nicolas wrapped up the bonus-point inside the half-an-hour mark, before Bosman got into the act for Stade's fifth before the break.
Parisse so often leads from the front, and he was at the spearhead of the second-half charge to make it 43-0 after the break.
It did not take much longer for them to rack-up the half-century, with Williams going over for his second score of the match.
Treviso finally got on the scoreboard after 58 minutes when Samuel Christie crashed over for a consolation score, and the game was done by the time Simone Ragusi and Marco Lazzaroni crossed.
