Australians are going to be a tough team to handle because of the combination and confidence they have at the moment,” Sachin told India Today.Australia rose to No. 2 with thrilling win against West Indies on Thursday. Fast bowler Mitchell Starc took five wickets. Highlights of West Indies vs Australia World Cup 2019 match “Australia at The Oval, it’s going to be a good game. The pitch has slightly spongy bounce and I think Australians are more used to that. Oval is one pitch where I feel there is a little bit of extra bounce which might favor Australia slightly,” Sachin said.Terming Australia a different side, Sachin hailed David Warner, giving the opener credit for the turnaround. “They are a different side (after Smith and Warner’s return). Whatever I saw of David Warner in the IPL, he looked extremely fit and above all he looked determined and motivated to go out there and get runs,” Sachin added. Warner had scored a fighting 89 in Australia’s tournament opener against Afghanistan.Sachin, however, was confident of India doing well in the match. “…But I feel Team India have the ammunition to go out and do what is required.The Australian attack is a good attack but Indian team is geared to play that attack. We have done well in the past against that bowling attack. Guys will be ready to face them,” Tendulkar added.
