FORMER Glasgow forward Leone Nakarawa may have been kept quiet at the weekend as his old team beat his new side Racing 92 in the Champions Cup. But Warriors assistant coach Kenny Murray has warned that the big Fijian and his team-mates will be out for revenge when they come to Scotstoun tomorrow.

Nakarawa did manage to steal a couple of Glasgow lineouts in his new club’s 23-14 defeat in Pool One. But on the whole the Warriors defence denied him the chance to play his usual dynamic game in open play - and Murray thinks a repeat performance will be required this time round if his team are to do the double over last season’s runners-up.

“He’s such an athletic sportsman,” Murray said about Nakarawa, who was a key player when the Warriors won the PRO12 title in 2015. “if he gets an early read on something then he can win the space and win the aerial battle quite quickly. That was an area of the game that wasn’t great for us, so that’s something we need to improve this week.

“He maybe wasn’t the same dynamic player he was here, but he’s still a massive threat. Obviously we knew him, we knew what his strengths and weaknesses were, so we looked at how can we ensure that he doesn’t go forward and attack. I thought we closed him down really well at times at the weekend, but we expect him to play this week, and on a 3G pitch that will suit his kind of game as well.

“We won’t change our structure and systems, but what we will look at is the fine bits of detail that we feel can get us an edge in the game. In defence it’s all about mindset, it’s about physicality, it’s about accuracy. And in attack it’s about taking advantage of the space that we get. I think one thing we did well over there was the tempo and speed we played at - they really struggled to deal with that.”

While the new pitch at Scotstoun may suit Nakarawa’s play, it will be unfamiliar to Racing. Glasgow, on the other hand, are used to the speed of the ball on the 3G surface, so can be expected to play a fast game. But Murray insisted there was no way they would write off the Frenchmen.

“They’ll be coming here to throw everything at us. We realise how difficult a game it’s going to be. Physically they’re a good side, individually they’ve got some of the best players in the world playing for them, but again we’ve got some good players as well and I think they proved that on Saturday.”

Meanwhile, Jason O’Halloran, who will become one of the Warriors’ assistant coaches next season, has turned down the offer of a position with the British and Irish Lions for their three-Test tour to New Zealand. Current Scotland assistant coach O’Halloran has decided that, with new head coach Dave Rennie possibly not being available until early August, he has to stay with Glasgow to help with pre-season training.

Jonathan Humphreys, who is also part of Vern Cotter’s Scotland set-up just now, is moving to Scotstoun with O’Halloran. Rennie is committed to remaining in his current post for as long as the Chiefs still have an interest in the Super Rugby tournament. The Super Rugby final is on 5 August.
