Adam Voges admits to underperforming in the Ashes, but the veteran is upbeat he still has a future in the Test side.

Voges could hardly have had a better preparation for the showpiece five-Test series.

The 35-year-old boasts extensive county experience, was coming off a record-breaking Sheffield Shield season and scored a century on Test debut against the West Indies.

Yet it failed to click in England, where he had a couple of starts but was unable to go on with it during any of the four Tests.

“My performances haven’t been great for this series,” Voges said.

“Our middle-order batting has been our real weakness. I was picked to do a job there and I haven’t done it anywhere near as well as I would’ve liked to.

“I’ve been a little bit tense … I haven’t been able to relax and get into my innings and play the game I would’ve liked.

“I’ve obviously been disappointed.”

The one exception was the second innings at Trent Bridge, where Voges pushed the game to at third day and delayed the inevitable.

Australia crashed to the inevitable defeat that was always going to follow a first-innings total of 60, their lowest in England since 1902.

Voges batted for over three hours, finished 51 not out and showed the exact sort of patience that was dearly lacking in the third and fourth Tests.

“I still think I’ve got plenty to offer,” he said.

“The second innings in Nottinghamshire I battled as hard as I possibly could and stayed out there for a little while.

“We’ll just wait and see.

“We’ll have those discussions at some stage, I’m sure.”

Coach Darren Lehmann and chairman of selectors Rod Marsh have both been tight-lipped about Voges’ future.

At a minimum, Voges should play the fifth Test that starts next Thursday.

Voges cited Chris Rogers, who has hit the peak of his Test career at age 37, as a source of inspiration and felt there were no major technique flaws he needed to fix.

“I’ve played one or two average shots. I’ve got a couple of good balls as well,” he said.

“It just adds up and it gets away from you pretty quickly.”

Voges is expected to play in Australia’s three-day tour game in Northampton, which starts on Friday at 8pm (AEST).

The squad, minus Michael Clarke who is in London, trained at the venue on Wednesday.

Lehmann and Marsh had a lengthy motivational chat with the squad prior to the session.
