Heineken Cup round-up: Arias on song as Scots get plastered in Paris

Stade Français scored four first-half tries against Edinburgh in Paris, on their way to a 31-7 victory in Pool Four of the Heineken Cup.

Julian Arias opened the scoring with a spectacular try off turnover possession and Sergio Parisse, Pascal Pape and Lionel Beauxis also scored tries. The former Leicester scrum-half Julien Dupuy kicked three conversions; Beauxis converted the fourth try and Dupuy's replacement, Noel Oelschig, kicked a penalty. The Scotland centre Ben Cairns scored a try for Edinburgh in the second half, Phil Godman converting.

Edinburgh's coach, Rob Moffat, said: "I'm not happy. We were poor in the first half and Stade are the sort of team that can kill you. We gifted them three tries. They are a quality side but you can't afford to be 28-0 down and expect to come back and win games.

"Stade can flick the switch on and play quality rugby but they did not have to show sheer brilliance today. We started OK, but then Stade capitalised on our mistakes. We showed plenty of spirit and character and actually 'won' the second half but we weren't ourselves in the first half.

"The players are disappointed but so are the coaching staff. We will look at what went wrong and see if it was good enough. We have to learn these harsh lessons and we must beat Ulster next weekend."

In Pool One, Benetton Treviso caused a huge shock by beating the French champions, Perpignan, 9-8 at the Stade Comunale Di Monigo. The Italian champions have a better European pedigree than any other club from their country – Wasps, Newcastle and Harlequins are among their past victims – but before yesterday's match they had lost 15 Heineken Cup home matches in a row.

Perpignan were beaten thanks to three penalties from the veteran South African fly-half Marius Goosen. The full-back Jérôme Porical scored a try and kicked a penalty for the Catalan side in the second half.

Life isn't about to get any easier for Treviso – their next match is at Thomond Park against Munster and Northampton are the next visitors to the Veneto – but this win will provide a tremendous fillip for the Italian game as preparations for next season's inclusion of two Italian teams in the Magners League continue.

The team who were beaten by Perpignan in last year's French Championship final, Clermont Auvergne, also had a tough time against Italian opposition yesterday, although they pulled away later in the game to win 36-18 at home to Viadana.

Brent Russell scored two tries for the French team and Thibault Privat, Vincent Debaty and Seremaia Bai also scored tries. The France scrum-half Morgan Parra kicked a penalty and three conversions and Brock James one conversion. Pierre Hola and Garry Law kicked three penalties each for Viadana.

In Pool Five of the Amlin Challenge Cup, Newcastle beat Petrarca Padova 29-27. A late try from the scrum-half Micky Young, added to tries by Ed Williamson, Danny Williams and Lawrence Ovens, secured a bonus point, although Petrarca missed a late penalty that would have won them the game.

Rob Miller kicked a conversion and a penalty and Jimmy Gopperth kicked two penalties for Newcastle. For Petrarca, the former Gloucester and France fly-half Ludovic Mercier kicked two conversions, a penalty and a drop goal. Stefano Ambrosio kicked a conversion and scored a try and Warren Spragg and Alberto Chillon also scored tries.

In Pool One, which also includes Leeds and Bourgoin, Bucharest won 21-9 at home to Overmach Parma.
