Carter's class sinks Grenoble
Grenoble suffered a 39-35 defeat at home to Racing 92 in a thrilling contest at Stade des Alpes at the weekend.
Bernard Jackman's men looked set for victory but Dan Carter inspired a late comeback by Racing, who emerged victorious to stay top of the table.
Grenoble led 26-21 at the break and were six points ahead with just seven minutes left.
But then Carter took a quick penalty and sent Joe Rokocoko over for a try which the All Black out-half converted to edge them in front.
Carter then wrapped up the win with a late penalty for a Racing side who are unbeaten in the Top 14 since November.
That win keeps Ronan O'Gara's men at the summit, with Carter converting four of their five tries in addition to a couple of penalties.
Grenoble got over for tries from hooker Loick Jammes in the opening half and James Percival after the restart.
Jonathan Wisniewski kicked seven penalties but it wasn't enough to prevent an eighth defeat in 14 games.
Grenoble, ninth on 29 points, this weekend travel to play champions Stade Francais, who are just below them in the table on 26 points as the season heads into a crucial stage.
The Parisians have also won six and lost eight but have only picked up two bonus points to Grenoble's five.
