LIONS MOVE IN FOR THE KILL

A flawless record of seven wins since arriving Down Under has placed the Lions on the brink of an achievement that has only been managed twice before in the professional era.

Successful Lions tours are the exception, not the rule, but they are overwhelming favourites to crush Australia for the second time.

The persistent rain forecast to fall throughout today could be a leveller, but on the strength of a one-sided first Test, Andy Farrell’s men should be comfortable winners.

DO OR DIE FOR AUSTRALIA

THE Wallabies are not just playing to keep the series alive, but also their credibility as a tour destination for the elite of British and Irish rugby.
