Watson sought to evade a question when he was indirectly asked if he was ready to captain the Australian side if Michael Clarke misses out the India series due to fitness issues.
"I am batting and bowling and have a big role in the team. I am not thinking about captaincy and I am happy to contribute with the bat and ball," Watson, who is playing for Rajasthan Royals in the Champions League Twenty20, said.
"We (Australia) played good cricket but few bad moments resulted in our defeat (in the Ashes). We could have won a few games but it was disappointing that we could not do it. The last six months since our tour of India have been good.
"We have a good batting coach and feel confident that we can win back the Ashes," said Watson after slogging at the the nets ahead of Rajasthan Royals' CLT20 match against Perth Scorchers here on Sunday.
