Warburton: ‘This is the first building block’

British and Irish Lions captain Sam Warburton focused on the positives after his side’s narrow 13-7 opening win in Whangarei.

The Lions trailed at half-time and for long periods were left facing the possibility of becoming the first touring side to lose their first match on tour since 1971.

Anthony Watson's try in the second half proved to be the decisive score, as the Lions held out for an unconvincing victory.

Speaking after the final whistle, Warburton admitted that the Lions had a lot to work on but added that the fixture would prove to be a big help when it comes to the squad's analysis moving forward.

The Lions' next game is four days away in Auckland when they will take on Super Rugby franchise the Blues.

"I'm pretty pleased with that," he told Sky Sports.

"They played with nothing to lose and you could tell that. It was good, at least we have some footage now to work on [defence] and to work on some attacking stuff as it obviously wasn't perfect."

"It is the first building block. We will get together now to support the guys playing on Wednesday [against the Blues] and to keep improving every week."
