Deans said he was extremely impressed with what he saw from the tourists and that Australia will need to match their opponents physically if they are to claim victory.

“I was very impressed with the Irish, especially their physicality,” Deans said.

“They have really developed some frames over the last few years.

“They are a group that has played a lot of rugby together, in particular in the respective units of up front and down back and they bring with them a lot of mentality.

“It’s their last game before a break so they are going to bring everything they have got and they will throw everything at us.

“They were pretty impressive around the contact last week and they will be pretty frustrated not to close that gate when it was possibly there to be done, so they will be looking to do that this weekend.”

Youngster James Horwill has been named to partner Nathan Sharpe in the second row and Deans said the duo will need to be at their best to match Ireland in that area.

“James has got the potential to match their forwards, but we are going to need that from everyone,” Deans added.

“We won’t be able to back off their physical confrontation and expect to succeed.

“We are going to have to engage Ireland somewhere and we are going to have to do well in that engagement.”

Saturday’s game is Deans’ first match in charge of Australia and the first Test the Wallabies have played this year.

Deans indicated that Ireland will be hold a significant advantage given they tackled the All Blacks last week and the European season finished recently.

“That’s the big point of difference for us this week,” he added.

“We are coming from a background of no Test rugby, while the Irish have had a game preparation. Some of our guys haven’t played rugby for close to a month and to step up to a Test match that is a big adjustment.

“You can talk it all you like but the reality of adapting to the physicality is significant and that is the first hurdle we have to overcome.”
