The 2018 winners made a perfect start to their campaign last week, seeing off Benetton Rugby 33-19 at the RDS Arena, with Henshaw coming on as a replacement after struggling with illness throughout the week.

Leinster face Lyon at Matmut Stadium de Gerland on Saturday and Henshaw warned of the threat that their hosts – who currently head the TOP 14 with eight wins from nine matches – pose this weekend.

“I suppose it’s a good way to get the ball rolling for us, to have the whole group back together,” Henshaw told Leinster’s website.

“We’d been back training about a week before that. Everyone was back on the same page. To put the hard work that we put in the last few weeks onto the pitch on Saturday night was brilliant.

“Away days in France are always a massive challenge. They’re top of the French league at the moment, have great, quality individuals and play good running rugby.

“The crowd is always on top of you and it just feels different. I suppose in a good way it’s good to be able to be in that position and embrace that challenge.”

Leinster were beaten at this stage last season, going down 28-27 to Toulouse at Stade Ernest Wallon, something Henshaw is keen to avoid this time around.

“We got the bonus point and we went away to Toulouse and we slipped up there,” Henshaw added. “I think one of the key components of that game was how we started as well. We had, I suppose, not the best start and they got ahead early, and then we were chasing.

“That was a big thing that we looked at. We’ll definitely speak about that. That’ll just highlight how we can’t take things for granted. We’re going over there and it’s going to be very tough.”
