Former Australian test cricketer Jason Gillespie has labelled the Australian cricket team as 'tired' and 'old' ahead of the first Ashes Test in July.

Gillespie, the current head coach of the Yorkshire County Cricket Club, called attention to the age of some of the Australian players and said that the English should attempt to wear them down.

"They're Dad's Army. I'd be thinking 'let's keep them out in the field.'

"Let's get them tired, they're old blokes. We can put these guys under pressure." He said, in an interiew with the Mirror.
