Norfolk's Ben Youngs insists all that matters is beating Australia this weekend to clinch a rare Lions' Test series win as he prepares to line up alongside older brother Tom.

The Aylsham duo will carve their own niche in Lions' history on Saturday when they become the first brothers since Scott and Gavin Hastings back in 1989 to start a Lions' Test match when they face the Wallabies in Melbourne.

The Leicester Tigers' scrum-half replaces Welsh rival Mike Phillips as Warren Gatland makes five changes from the starting XV who held on for a tense 23-21 opening Test victory in their bid to clinch a first series win since 1997.

'All I want to do is go out there and play well and hopefully win the game and the series and then we can come off together and really treasure it,' said Ben.

'I'm just trying to focus on the game now and not get too distracted by all the things that go with it. I think we are in a great position and it is just wonderful to be part of this great tour. To now have the opportunity to run out this weekend and play a part will be a moment to remember.

'We have tremendous strength and a huge amount of experience in midfield. You look at people like Drico (Brian O'Driscoll) and guys like that who have the strength to get us on the front foot and the forwards as well to lay the platform.'

Lions' first choice hooker Tom was outstanding last weekend, but the 26-year-old is adamant the tourists will have to improve dramatically to quell an expected Australia backlash.

'We all understand and realise there's still much more to come from this side,' he said. 'We didn't play to our full potential, but we still managed to win the game. That gives us such a boost heading into the second Test. Believe me, we have learnt so much from the first game. We didn't play all that well, but we dug out a win. We all know we can take our game to another level. We go into the second Test with momentum behind us.'
