Glenn Maxwell insists he has the right technique and temperament to forge a consistent Test career. By leaving him out of the Ashes squad for next week's series opener in Brisbane, the national selectors, certainly in the short-term, still have their doubts.

Maxwell has every right to feel aggrieved by the decision, for he had played in Australia's past four Tests. However, his lack of productivity to start the new season, particularly on day one against Tasmania this week, cruelled his hopes. At a time when the selectors were looking for potential No.6 batsmen to shine like a beacon, Maxwell's form only flickered.

National selection chairman Trevor Hohns on Friday said Maxwell and Hilton Cartwright, who both played in Australia's last Test, against Bangladesh, had squandered an opportunity.

"Both of those fellas obviously were spoken about and, once again, we came up with the fact they haven't performed well enough in the early rounds of the competition this year. As I suggested, they were going to be crucial rounds for everybody and everybody knew there were positions up for grabs. It was up to them to perform and present their case to us," he said.
