JOHNNY Sexton will prove his "world-class" abilities all over again in New Zealand after a tough opening with the British & Irish Lions, according to Greig Laidlaw.

Sexton fluffed his lines with his worst performance in some time as the Lions laboured to a 13-7 win over the New Zealand Provincial Barbarians.

The Ireland playmaker must surely have ceded ground in the race for the Test number ten shirt, especially as Owen Farrell replaced him in Whangarei and dragged the lacklustre tourists to a slender victory.

Yet Scotland scrum-half Laidlaw insisted that Sexton can still turn his poor start on its head and restore his much-vaunted reputation.

"We know the class of Johnny, who is a world-class player," said Laidlaw.

"For nines and tens, we probably have the hardest job trying to organise everything around us and concentrate on our own game.

"It's always a little bit tougher and when the heat is on, everyone is looking to you to make the calls. Johnny will be back up and running next time he pulls on the jersey.

"The more you play together, the more he would know what I was going to do, just building the relationship. It's about making sure you do that by practising hard in training going forward."

Maintenance engineer Sam Anderson-Heather's try put the Barbarians 7-3 up at half-time in Whangarei but the Lions squeaked home thanks to Anthony Watson's late score.

The Lions will now face the Blues in Auckland on Wednesday as the New Zealand tour cranks through the levels – but Laidlaw insists that Warren Gatland's side can quickly hit their stride after a poor start.

"I am absolutely delighted and very honoured to have worn the jersey," said Laidlaw.

"Now I have got the taste of it, I want to get out there again. Next time I get an opportunity, I want to get out there and play again.

"There were a lot of positive things from the coaches. They were delighted with the win and just want to keep pressing on now, keep getting better day in, day out and making sure next time we take the field we are a bit better so we can go on and win more games.

"It was very calm at half-time, which was good. It was calm heads and calm voices which we had, just to be able to build that second-half performance.

"We were hanging on at times in the second half, so it was good messages at half-time and we came out and executed in the second half.

"We stepped off the plane and were straight into it – but we are happy to win. We created opportunities, even though we obviously didn't take them. We would be a lot more worried if we weren't creating opportunities.

"Time together in the saddle will be very important now in training, putting together combinations and the team that goes out together on Wednesday. That is the next task in hand. We need to make sure we go and win that now."
