The Irish province are three from three in Pool B to lie third, a point behind joint leaders Harlequins and Leicester Tigers, and have a nine-day turnaround, with their 16-13 Round 3 success at Castres Olympique having taken place last Friday.

“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,” said Van Graan.

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

“We’ve put ourselves in a really good space, so it’s a massive game for us against Wasps next Sunday.”

A 78th-minute try from Gavin Coombes, converted by Jack Crowley, wrapped up the victory at Stade Pierre Fabre.

“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.”

Having said that, like any coach, the South African picked out some areas to improve next time out at Thomond Park.

“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,” he pointed out. “The one that mattered, though, we finished.

“I thought we had some very good attacking passages. One or two balls went to ground in the 22, but I thought from a performance point of view, there was some really good stuff.”

Although Munster Rugby have already qualified for the last 16 of the Heineken Champions Cup, head coach Johann van Graan stressed that they would be going all out for victory against Wasps next Sunday in a bid to clinch a home tie.
