London Wasps celebrated their 100th European game in style, beating Bayonne convincingly 25-11 at home to move top of their Challenge Cup pool.

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, flank Sam Jones 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 centre 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 the 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.

Stade Francais Paris 45-3 Banca Monte Crociati

Stade Francais Paris heaped more pressure of Worcester Warriors in Pool One of the 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 One.

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 flank Pierre Rabadan rounded off a good night's work with a try with the final move of the match.

The scorers:

For Stade Francais:
Tries: Pape 2, Rabadan, Sempere, Lyons, Camara, De Malmanche
Cons: Fillol 3 , Plisson 2

For Crociati:
