Head coach Johann Van Graan was proud of his Munster side after they came from behind to make it three wins from three in the Heineken Champions Cup with a hard-fought 16-13 win at Top 14 side Castres.

Gavin Coombes crashed over in the 78th minute to snatch the win that ensured qualification to the knockout phase of the competition for the province.

"You don't just come here and win," Van Graan said. "We spoke about an 80-minute performance and we certainly got that.

"Everybody gave it their all and we're very happy with the four points."

Despite being an 80-minute performance, it was not a perfect one, Van Graan admitted. He said: "We had one or two uncharacteristic errors with the lineout five metres from their line - one in the first half and one after 70 minutes.

"You have to give credit to Castres' defensive lineout as well. They took a chance - not a lot of teams contest five metres out ... and one or two balls went to ground in the 22, but I thought from a performance point of view it was impressive stuff."

And he heaped praise on matchwinner Coombes, describing him as "a massive part of our group".

He said: "I thought he was phenomenal tonight."

Now qualification is assured, the focus shifts to next weekend's final pool match against Wasps at Thomond Park.

"We only had our focus on Castres tonight - this was a really good result for us. We are three from three in Europe," Van Graan said.

"We play next Sunday, which gives us a nine-day turnaround, so we'll take the three days and recover - it was a short, six-day turnaround from our previous game against Ulster.

"We'll regroup and look at our resources - obviously, in this competition, if you're good enough to go further, home advantage is crucial.
