ICC World Twenty20: Shane Watson says facing India 'ultimate challenge'

Australia all-rounder Shane Watson says playing India in a knockout match before thousands of home fans Sunday will be the "ultimate challenge."

The Indians and Aussies are tied on four points each from three games, which means the winner of Sunday's Group 2 encounter in Mohali will advance to the World Twenty20 semi-finals alongside already-qualified New Zealand.

"It is the ultimate challenge to play India in any format here in India," said Watson, who confirmed earlier this week that the tournament will be his international swansong.

"If you can beat India on Indian soil in any format, it's an incredible achievement. Everyone in the Australian team knows that.

"I certainly know that from plenty of experience here, so it's just going to be a great challenge and we certainly are going to be up for it."

An Australian victory would knock India out of the tournament and ensure Watson gets to play at least one more match at the highest level of the game.

"From my personal perspective, to have the opportunity to be able to play in what could be my last game is, I suppose, as big a dream as you could imagine," he said.

"So it's going to be very exciting," added Watson, who has 46 wickets and 1,444 runs from 57 T20 internationals so far.

Australia are the reigning 50-over world champions and the No 1 Test side, but have failed to win the World T20 in five previous attempts.

Watson says India - who pulled off an astonishing win over Bangladesh, taking three wickets off the last three balls - will start the game as favourites on home soil.

He said: "One thing about India is they are such a dangerous side. They haven't clicked so far in this tournament. But they have got world class players for all types of wickets. And with their world class players, when they click they are really unbeatable.

"We know that we have to put them under pressure straight up to try and give them less chance of clicking as a team."
