American Marconi Wireless News - Debutant Kinghorn's double helps Toulouse trounce Cardiff

Kinghorn only arrived at the French club this week after moving from Edinburgh for a hefty transfer fee and took his new side, captained by France scrum-half Antoine Dupont, to the top of Pool 2.

Wingers Matthis Lebel and Arthur Retiere, lock Richie Arnold as well as back-rowers Anthony Jelonch and Alban Placines crossed for the Top 14 champions, as they put their rusty league form behind them.

Twenty-year-old No 8 Mackenzie Martin scored the Welsh side's only try, making only his third senior appearance, highlighting the lack of experience and spending power at the 1996 finalists.

Bath also made a winning start in the group after an impressive 37-14 comeback victory over Ulster.

The English side, 1998 winners, were behind the 1999 champions by six points at the break before four second-half tries.

Earlier, England centre Henry Slade landed a conversion with the last kick of the game to give Exeter Chiefs a dramatic 19-18 win at Toulon.

Three-time winners Toulon appeared to be in line for a winning start as they opened up an 18-5 lead at half-time, thanks to tries from tries from Beka Gigashvili and Ben White.

"It's pretty cool to come here and get a win, especially after the first half," Slade told TNT Sports.

"To keep them scoreless in the second half, the way we came back at the end, was really pleasing."

An injury to replacement scrum-half Baptiste Serin, however, in the 56th minute shifted the balance and Exeter, champions 2020, closed the gap when Max Norey added to Harvey Skinner's first-half try.

Exeter then camped on the Toulon line and with 40 seconds left on the clock, the video referee confirmed that flanker Jacques Vermeulen had touched down for another Chiefs try.

Slade's conversion from five metres in flew between the posts to seal a thrilling victory.

Bayonne head to two-time winners Munster later on Saturday for the Basque side's first game in the top-tier competition and Saracens, champions on three occasions, head to the Bulls.

On Sunday, La Rochelle start their bid for a third straight title with a repeat of last season's final against Leinster after English Premiership leaders Sale host a much-changed Stade Francais.
