"Yesterday, I said 3-0 but I stuffed up because I thought there were only three Tests. But definitely 4-0 now," said McGrath at the SCG where he was promoting McGrath Foundation for breast cancer.

"The way the guys have played at the moment I've been very impressed. I think a team builds itself around a bowling attack and you look at the bowling attack the team has at the moment.

"It will give the rest of the guys a lot of confidence so I'm very confident, as confident as I've been in years that this team is something special and expecting big things from them too," he added.

McGrath had words of praise for pace bowling sensation James Pattinson.

"I've been very impressed to look at James, the way he comes on to bowl. He's big, he's strong and he's nice and tall.

"He has a good action, he bowls in great areas and got good pace and a great attitude. I've really enjoyed watching him bowl and getting stuck into the Indian batsmen," he said.

Pattinson was man of the match at the MCG for his seven wickets and unbeaten knocks of 18 and 37 in two innings. Above all, he breathed fire and bowled with aggression at the Indians.

"Definitely, it's all about attitude and we're fast bowlers at the end of the day. You don't bowl half volleys and skip around the park smiling at batsmen, do you?" said McGrath.

"I wish I could bowl that quick and it's been a great start for his career to have a couple of five-wicket hauls under the belt. The confidence has got to be up.

"I think he's got a huge future. I wish I started my career as well as James has so I'm expecting huge things from him definitely."

The great fast bowler, who took 563 wickets during his career of 124 Tests, said Australia would do no harm if they opt to play four fast bowlers in this Test.

"It has spun in the past in Sydney. I like a spinner in the team as a bit of balance but with Ryan Harris with the form he was in before he got injured to bring him back into the team would offer so much and especially playing India in Australian conditions.
