Earlier a Ronan O'Gara penalty and his conversion of Sean Dougal's 15th minute try had Munster leading Racing 10-3 with 28th minutes gone at the Stade de France. Then a mistake in the backline handed the home side the opportunity to level. And Barkley then kicked a penalty before the break to leave the home side 13-10 in front at the break.
