Munster have recorded anther success in the Heineken Champions Cup, despite playing the majority with 14 men and failing to register a second half score until the 75th minute.

Munster started better and after Mike Haley collected a highball and went on a mazy run before he was brought down by Northampton, they were penalised at the breakdown and Joey Carbery stepped up and landed the kick for a 3-0 lead after two minutes.

Things would get better for the hosts, another penalty saw Carbery to kick to the corner, they executed the lineout perfectly and forced another penalty that they took quickly with a little tap and go as Gavin Coombes charged over from close range with the conversion giving them a 10-0 lead after ten minutes. Northampton had a double blow as just after the try Mike Haywood was shown  a yellow card for a high tackle on Joey Carbery.

With the extra advantage Munster kept up the pressure, another trademark move saw them gain ground, a gap opened out wide with Coombes darting on the wing, he didn't have the gas to get over for a second try but offloaded to Jack O'Donoghue to work the score, Carbery on hand to make it a 17-0 game after 21 minutes..

While it was going all the way of Munster just seconds later Jack O'Donoghue was sent off after going too high going into contact and his shoulder made contact with David Ribbans' head, no choice that it was indeed a sending off.

The card did little to stop the Munster machine from following in a further score,  Coombes powering over from close range with the support of his teammates, Carbery making it 24-0 off the conversion.

The second half would start with Munster on the back foot, the visitors carried well through their forwards before going wide where they had an overload, as Tommy Freeman got over with Fin Smith converting to reduce the gap after six minutes past the restart.

Smith landed a penalty minutes later to again chip away at the Munster lead before they hit the jugular before the hour mark, after a kick and chase to the corner by the Saints Joey Carbery was back to gather the ball but support failed to come quick enough and the ball was turned over for James Ramm to score, Smith reducing the gap to 24-17.

Agan Munster found themselves penalised this time for not rolling away and Northampton fly-half Smith narrowed the gap to four points after 71 minutes, eventually after 75 minutes Munster got on the board in the second half as Jack Crowley stepped up to slot a penalty to push them ahead 27-20.

Shane Daly made a match winning try late on to stop the Saints having a chance at a late try to equalise, but they would get a penalty to leave it a four point margin at the end.
