James Lowe proved once again a thorn in Munster's side and Johann van Graan could offer nothing but praise for the New Zealander.

The Leinster winger stood out in last season's Guinness Pro14 semi-final win over the Reds and came away from yesterday's affair with two more tries to his name – and but for an early tackle by Keith Earls he would have had a hat-trick.

"He's one of those world class players," van Graan told RTÉ Sport after the 30-22 defeat. 

"You've got to cut down his space. He did pretty well in that semi-final last year as well.

"You've got to say well done, I thought he played really well."

The 26 year old made 53 metres with the ball, carried 11 times and made two clean line breaks, lighting up the Aviva on a beautifully clear autumn evening.

Leinster coach Leo Cullen added: "James is a handful for defences, very, very strong in contact, and he's gone well the last couple of weeks. He's a constant threat and he's into everything, he's a good addition for us.

"He has become very passionate about the team, which is good. It's what you want.

"It was tough for him last year when you think back to, this time last year he was playing the Mitre 10 competition so he wasn't here, and he came off a Super Rugby competition with the Chiefs and then the Mitre 10, which is quite intense. 

"It was a challenge for him and we couldn't register him for Europe at the start as well. It's nice for him to have got through the season, got up to speed eventually and he had a decent pre-season as well. He's been good."

Despite his form Lowe may not retain a place in the squad for next week's Champions Cup clash with Wasps, with Scott Fardy and Jamison Gibson-Park also in the running for the two non-European spots on offer.

"Everyone is in the mix," said Cullen.
