Australia, on Friday secured a last-four spot after defeating Pakistan by 6 wickets in the third quarter-final at Adelaide Oval.
This set up a second semi-final meeting in Sydney (March 26) with India for Clarke and his men. India had confirmed their berth yesterday (March 19) with a convincing 109-run victory over Bangladesh in Melbourne. So far India have been unbeaten in the tournament, winning all 7 matches.
When Clarke was asked about facing India, he said they were in good form and playing well. He also praised captain MS Dhoni.
"They are in good form. They are playing well. MS Dhoni is leading them very well," Clarke said after the match in Adelaide. "It will be a tough challenge," the skipper added.
The last time India and Australia faced off in a World Cup was in 2011 when Dhoni's team knocked out Ricky Ponting's side in the quarter-final in Ahmedabad.
