Brendan Roberts says he has 'unfinished business' in the World Superbike Championship as he continues to sit on the sidelines following his injury in a crash at Monza.

The Australian started the year with the Guandalini Ducati team, but had managed just a single points finish in the opening eight races before he was involved in the first turn accident in Italy, one that also went on to sideline Max Neukirchner, Makoto Tamada and Troy Corser.

Since then, Roberts has been on the road to recovery, but he admits he remains unsure as to whether he will be back on the same bike before the end of the season.

"The state of play is I am on the sidelines and looking to get back on a bike," he told Radio. "The injuries include a hole in the quad muscle and a haematoma, but they are repairing themselves. Fingers crossed, the next few weeks I can get on a bike and keep myself in there, but back in the World Superbike paddock is where I want to be.

"I have more to prove. Last year testing for the Xerox Ducati team I was fast on a track I didn't know, so I feel like I have unfinished business. I think I can go better if I have the right equipment, but I have been trying to learn and trying to go fast, which is difficult when you put them together."

Looking back at his Monza accident, Roberts says he is sorry for getting caught up with Neukirchner when he tumbled at high-speed, but adds he was in danger of taking down considerably more riders had he not taken to the grass.

"I like watching it [the accident]," he joked. "I actually led a World Superbike race for about two seconds. All jokes aside, I know what happened in that I was hit from behind by Tamada and I accelerated with all the brakes on, so I made a split second decision to go onto the grass otherwise I may have cleaned up twenty blokes. I was unlucky it rained the night before, so straight away I was on my arse!

"Unfortunately I took out Max and we both ended up in hospital lying next to each other, twenty hours of having a chat and a laugh - even though it wasn't very funny!"
