Sydney, Dec 4 (IANS): Australian fast bowler Ryan Harris Thursday said he is both physically and mentally fit to make a comeback to the national squad, to play the first Commonwealth Bank Test against India starting Dec 9.

Harris has vowed, the team will be maintaining their aggression when they turn out for the first Test at the Adelaide Oval.

The bowler who joined compatriots at Phillip Hughes funeral Wednesday in Macksville stated that the experience was indeed emotional which convinced him he was ready to play.

Harris wrote in a Fairfax Media Column, which was published in Cricket Australia’s website: "Seeing the green and gold streamers was a reminder these people want to see some cricket played, want to see us get out there and beat the Indians."

He also spoke about how the mood changed for the players after the funeral.

There were conversations about getting back into the field, but he also believed Hughes would be at the back of their minds.

"We're going to have our mate in the back of our minds - there's no doubt about that - but when we walk out onto that ground we need to try and focus on our game thoughts, where we need to be to be ready to play," said the pacer.

"We'll definitely be maintaining our aggression; that's how we play well. That's what we do. That's the Australian way so we'll get back to doing that. It's what those people I walked past Wednesday in the procession would want, and what they would expect."

Harris, though, was unsure if Australia could field a full strength side, for the first Test, as most players have not picked up the ball or bat after the death of Hughes.

"I'm in good shape. I don't have any doubts about my fitness," he added on his fitness.
