Third TestAustralia    vs    British and Irish Lions    1pm SS1SYDNEY. Australia are confident they can fulfil their coach’s prediction and produce their best performance of the series in the decisive third test against the British and Irish Lions on Saturday.Robbie Deans said on Thursday he thought his team would be at their best in the crunch match at Sydney’s Olympic Stadium and finish what has been an incredibly close series with an "emphatic” display.The Wallabies scored two tries in the first test defeat through winger Israel Folau and the only try in their victory in the second match last week in Melbourne but scrumhalf Will Genia felt they had not yet hit their stride."We’re very confident,” he told reporters on Friday."We can honestly say we haven’t played our best footy throughout the series thus far and probably made too many errors to give ourselves an opportunity to play any sort of fast, flowing rugby."I think we have been chasing the game a little bit too much in the last two tests and playing off the back foot."So if we can start well and give ourselves a good opportunity to get into the game then we definitely back ourselves to play some good rugby and really have a go.”Key to getting front foot ball will be the Wallabies pack continuing to at least hold their own against their Lions counterparts both at the set piece and the breakdown.
