London Wasps celebrated their 100th European game in style, beating Bayonne convincingly 25 v 11 to move top of Pool 3.
The hosts got off to a flying start and never looked back as they attacked with fluency and control from the kick-off.
Captain Joe Hart nearly crashed over in the first minute but was held up over the line but it took just a minute more for Dai Young's side to record their first try, flanker Sam Jones on his 21st birthday touching down.
Nicky Robinson added the extras for the hosts and then kicked a 17th minute penalty to stretch the former European Champions' lead.
Benjamin Boyet opened Bayonne's account with a penalty two minutes later before Robinson slotted over his second.
Wasps controlled the territory for long phases but lost Riki Flutey to the sin-bin after he was penalised at a ruck and Boyet kicked the resulting penalty to double Bayonne's score.
In their first threatening attack of half, Sione Lauaki picked up from the base of the scrum for Bayonne and powered over from close range to score two minutes from the break. Boyet couldn't add the extras from out-wide, leaving Wasps in the lead at the interval.
A huge penalty kick from Elliot Daly followed by six points from the boot from Robinson stretched Wasps advantage once again as they dominated the third quarter.
Brive 38 - 13 CR La Vila (Pool 5)
Brive made it four wins out of four in the Amlin Challenge Cup this season with a bonus-point victory over CR La Vila at Stade Amédée-Domenech.
The French side got off to a flying start with Benjamin Caminati touching down after just 5 minutes. He then converted his try and was lining up his next conversion just two minutes later following Scott Spedding's score.
Louis Acosta was next to touch down for the hosts and Mathias Atayi crossed for the bonus-point score after 22 minutes.
La Vila fly-half Nick McCashin grabbed a penalty back for the visitors after 37 minutes but Brive had the last word with a try from Alexandre Bias.
The Spanish side were the first to score in the second period though, Nathan Reid touching down. McCashin converted and then kicked a 58th minute penalty.
Brive's only score in the second period came from Mathieue Belie but the hard work had been completed in the first period and they stay in command of Pool 5.
Bordeaux Begles 15 - 10 Femi CZ Rovigo (Pool 3)
Bordeaux completed the double over Rovigo on Thursday evening but were made to work hard for the victory by their Italian visitors.
Bordeaux raced into an early lead courtesy of a Borid Bethery try after eight minutes but Rovigo responded with a try of their own through Roberto Pedrazzi.
Samuele Pace converted the score to give his side the lead and Davide Duca kicked them further ahead with a drop-goal.
The second period though was all Bordeaux. All of their second half points came from fly-half Nicolas Sanchez who kicked a penalty before scoring a converted try of his own to seal the win.
Stade Francais Paris 45 - 3 Banca Monte Crociati (Pool 3)
Stade Francais Paris heaped more pressure of Worcester Warriors in Pool 1 of the Amlin Challenge Cup as they comfortably completed the double over Italian outfit Crociati to move nine points clear at the top.
Worcester face Bucharest Wolves at Sixways on Saturday afternoon and must pick up another five points if they are to stay in touch with the French side and give themselves any chance of overturning their home defeat by the Parisians in Round 1.
French lock Pascal Pape was the man who brought up the bonus point for the home side with the second of his two tries after 50 minutes and Michael Cheika's men ended up with seven in a comfortable 45-3 win.
Wing Djbril Camara and hooker Laurent Sempéré crossed for first-half tries as Stade went into a 12-3 interval lead. Then came a quick one-two from Pape to secure the bonus point and it was plain sailing from there on.
Replacement hooker Aled de Malmanche and Australian international No 8 David Lyons got further tries before skipper and flanker Pierre Rabadan rounded off a good night's work with a try with the final move of the match.
