@James Casey that is a mistake, it should be 4 points for a win, 1 try bonus point for 4 or more tries and 1 losing bonus point for losing a match by 7 points or less.

FULL TIME! That's the full 80 here in Cardiff as the Blues walk away with a well deserved victory. This has been the best possible opening to Cardiff's European challenge as they earn the bonus point on top of their win. Unfortunately for Grenoble, they were unable to break down the home side's defense often enough to earn the points. Although this is only the first round of the competition and both sides still hold a strong chance of qualifying! Man of the match in my opinion is Rhys Patchell for his superb kicking game.

Are Challenge cup wins only worth 2 points in the pools? Or is that a mistake?

Try for Grenoble! It has taken the whole match to break down Cardiff's defense but Grenoble have successfully gone over for their first try, scored by Marrou. Unfortunately it is too little to late for the away team.

Cardiff relentless in their attack as they continue to apply pressure as we reach the last few minutes of this game. They earn their fifth try of the game through Turnbull to give them a commanding lead of 37-9.

Ten minutes remaining here at Cardiff Arms Park. The score remains 30-9 to the home side. Grenoble will have to push hard if they want to win this game.

The fourth try for the home side scored by Richard Smith. Cardiff have earned the bonus point!

Cardiff refuse to allow Grenoble to get back into this game as they open up their winning margin yet again.

The third penalty kick converted by Hart in succession, as Grenoble look to get back into this game.

TRY! Cardiff open the second half just as they begun the first, with a try early on. Warburton adds his name to the scoreboard as he goes over for his first try of the game. Patchell converts.
