Johan Eramsus admits that Racing 92 second row Leone Nakarawa requires some extra attention.

Munster host the Top 14 side, top of Champions Cup Pool 4 courtesy of a 22-18 win over Leicester last week, tomorrow at Thomond Park (5.30pm).

The visitors boast the likes of former All Blacks Dan Carter and Joe Rokocoko as well as France stars Maxime Machenaud and Yannick Nyanga in their line-up but it’s the giant Fijian that has that X factor, according to Erasmus.

In fact, the 29-year-old leads the offload chart to date with 10 - twice as many as any other player - and scored a try in the win over the Tigers.

"The boys know him pretty well from playing against Glasgow and obviously last year we played against him," the Springboks-bound coach told RTÉ Sport.

"It seems like you make [plans] for him, he just grows another arm and gets another offload away.

"When you focus too much on him then the other strike-runners really feed off him so we’ll have to get our house in order and specifically focus on him, knowing we can’t leave the other guys out of it.

"We’ve played him a few times and he’s really got stuck into us and created some great tries so that’s one of the big challenges in their team."

Munster were far from impressive last week during their 17-17 draw in Castres and Erasmus conceded that they were lucky to emerge with two points.

But the 45-year-old knows that Thomond is a unique venue for European rugby – Munster have won 28 of 30 games there – and can’t wait for the kick-off as the Paris side hope to break a run of four away Champions Cup defeats in a row.

He added: "My eyes were opened last year, the first one was obviously Glasgow.

"I was surprised about how a match can turn into an atmosphere like that and after that it just got bigger and bigger.

"Racing have been here and played against that atmosphere, it won’t really bother them that much."
