Former Indian skipper Dilip Vengsarkar has suggested Michael Clarke's side is the worst Australian team ever to tour India.

And the results so far, of losses by eight wickets and by an innings and 135 runs add weight to the theory from Vengsarkar, who is also a former Indian chairman of selectors.

Vengsarkar says Clarke - who unlike every other batsman in the touring team's top six is making a strong contribution - is the only person who seems to be trying his best.

"Going by the way the Aussies folded on the fourth morning at Hyderabad (all out for 131 in their second innings in the second Test on Tuesday), one is tempted to ask whether this is the worst ever Australian team that has toured India so far," Vengsarkar wrote in his column in The Times of India on Saturday.

"However at Mohali the conditions might just help the Aussies. Will they show enough spunk to put it across the Indians?

"A tall order, but in cricket nothing could be ruled out."

The Mohali pitch for Thursday's third Test is expected to offer more pace and bounce than the low and slow decks in Chennai and Hyderabad where India's spinners dominated.

Australia's hopes of winning a Test series in India for only the second time in the past four decades have gone following their massive defeats in the first two matches.

However Clarke says Australia remain confident of fighting back to level the series two-two and retain the Border-Gavaskar Trophy.

It remains to be seen whether Vengsarkar's sledge will motivate the Aussies, who copped a similar shirtfront in the media ahead skipper Allan Border's venture to England in 1989 for a shock Ashes series victory with a lineup that was also inexperienced.
