Carlos Checa is expecting Max Biaggi to pose the greatest threat to his hopes of completing a clean sweep at Phillip Island after just 0.013secs separated the pair during Superpole.

Having now topped every session - including the three Superpole phases - this weekend, Checa remains the hot favourite to repeat his 2010 victory around the Australian circuit.

However, despite setting a new lap record during Superpole, Checa was given his sternest test yet by reigning champion Biaggi, who got to within two hundredths of a second of causing an upset.

Indeed, while Checa is unconcerned about the steadily decreasing margin for error, he admits Biaggi will be tough to beat come race day.

"In the end it was a very hard-fought Superpole but we are of course happy to have closed in pole position," the Althea Ducati rider said. "We knew that it would be more difficult with qualifiers which usually bring riders' times closer together. To start from the front of the grid is obviously valuable but I'm aware that I also need to make a good start to the races.

"Let's say that I don't trust anyone, in the sense that tomorrow will surely be a battle! We'll see tomorrow how best to manage the situation but I think Biaggi will be my main rival. I am however determined to bring home two great results."

Checa's pole position is the third of his WSBK career and only the second by a Ducati rider since 2009.
