Johann van Graan says he takes responsibility for Munster’s performance in their 24-point defeat to Cardiff but added that he got "answers" about some of his players.

Munster have won both of their Guinness Pro14 home games this season but the 37-13 reverse was their second loss on the road from two away games.

With the interprovincial derbies and the Champions Cup on the horizon, the South African was asked how close his was to formulating his best starting XV.

"I got a few answers out there," he said.

"I thought there were some good individual performances and I think one or two of the guys inside will be very disappointed with their individual performance.

"But I take responsibility; it wasn’t good enough from us as a side. We’ll go back to the drawing board, take it on the chin and move on."

Munster trailed by a point at the break, 14-13, with Ireland winger Andrew Conway scoring two tries.

At 24-13 with a quarter of the match to play, Munster piled on the pressure but conceded a penalty under the Blues' posts. 

Van Graan saw that as a vital turnover.

"It was a huge moment in the game," he said.

"I thought that would have put us right back in the game but no, that’s why it’s called rugby.

"This is a game for men, you need guys to win big moments and well done to him, he won that one. "

Munster's next game is against Ulster at Thomond Park on Saturday 29 September.
