Lawrence Dallaglio is calling on the British & Irish Lions to be ruthless in claiming glory against Australia in Melbourne on Saturday.
Warren Gatland's tourists head for Melbourne having edged the first Test 23-21 in Brisbane - and Dallaglio is urging them to retain a keen focus on the prize of a first series win in 16 years.
The former England captain, who toured with the Lions in 1997, 2001 and 2005, said: "You always have to be wary of a wounded animal and on this occasion it's a wounded Wallaby. They'll be very dangerous because it's all or nothing.
"The intensity Australia showed last weekend was outstanding for a side that hasn't played for six months.
"The team selection for the Lions is almost as if they had lost last weekend because Warren Gatland is clearly saying by the changes he's made that the performance wasn't good enough.
"The Lions know they will have to be better if they are to win tomorrow and there will be no complacency at all.
"There are a lot of key drivers there - people like Brian O'Driscoll who are desperate to be part of a winning Lions series.
"Having gone 1-0 ahead rather fortuitously, they have an incredible opportunity to close out the series and do something that history says is very rarely done.
"The Lions have the momentum and that is key - they have two bites of the cherry now. There's a lot of pressure on the Wallabies."
