Dave Warner Feels Guilty Over Mickey Arthur Sacking On the outer ... Dave Warner at Nottingham earlier this month. Gutted by the knowledge his behaviour contributed to the sacking of a coach and his exclusion from the Test team, David Warner can now truly say that he understands the consequences of his actions. Warner boarded a plane to Zimbabwe on Tuesday intent on reinventing himself as a solid citizen of the Australian team and a No.6 batsman in the Mike Hussey mould. I know if I stuff up again I'm on the first plane home. No-one needs to tell you that because you already know it. In the month since he punched Joe Root at the Walkabout during Australia's Champions Trophy campaign, his words have been backed up by actions. Sacked ... Former Australian coach Mickey Arthur. Warner said he broke down on the phone to his parents after he was told he wouldn't be playing in the first Ashes Test. If the penny hadn't dropped for the wayward batsman before, it did then, and did again as he headed to Heathrow while his teammates got ready to play the second Test at Lord's. Warner's suspension only applied to Australia's warm-up games - lenient compared with the Test ban handed to the four players stood down in India. But his punishment kept on giving when the selectors judged the 25-year-old too much of a risk for the Trent Bridge Test without match practice, then sent him to Africa to get some with Australia A, where he will bat at No.4. He is due to return to the Ashes tour between the second and third Tests. It was massive to miss a Test. As a kid growing up you want to play in the Ashes and after that incident I went back to my room and I was pretty shattered for a week and a half, two weeks. I still feel the guilt of what happened. I feel it's led to me being in this situation at the moment. Things would have been different, I would have been able to play those warm-up games and I could have pressed my claims to play in this first Test but that's me. I put my hand up and accepted the consequences. Now it's about putting as many runs on the board as I can these next two games, Warner said he owed it to his teammates to lift his standards. A hundred per cent I do. Because I stuffed up. There's a lot of contributing factors to certain things that went on around the team. No-one likes a guy disturbing their preparation and that's what I felt I did, especially with the Champions Trophy. All that stuff came out before that game against New Zealand. I didn't play and then it was about me and not about the team's focus and that was the most disappointing thing. Australia could use an in-form Warner in light of its batting struggles, and he said felt in his teammates' debt. Warner's behaviour was a problem before the Walkabout incident; Mickey Arthur imposed a curfew in the West Indies last year, and his failure to uphold off-field standards were seen as a slight on the coach. It was probably another thing that was gutting, that I may have played a part in that [Arthur's sacking]. New coach Darren Lehmann wiped the slate clean but Warner is under no illusions about what will happen if he transgresses again. No-one needs to tell you that because you already know it," he said. [Lehmann] just said to go out there and score runs and be myself. Just get that X factor back that I can have for this team so hopefully I can score some runs. Definitely still enjoy myself off the field. There's no bans, there's no curfews, no nothing. The mistakes, I've learned, I've become more mature off the field as well. Warner said he had started thinking more about the things he can do to help the team, and what he has to do if he is to become a better batsman. If I get into this team and I bat six, I'll be doing everything I can to fill that Mike Hussey role and come out and have that intent from ball one, because I see that as the acceleration number in the team. Lehmann has already noticed a more diligent approach to Warner's fitness and training. That's something I picked up from Mike Hussey and Ricky Ponting. You would be up in the changeroom about to have a shower and you would look out there and go, 'Why are they still out there? You actually start learning that to help your teammates you have to do those extra things. A lot of the guys do that. I've caught on that you have to give this 100 percent not go at 60 or 70 percent and be content with that. You want to be the professional athlete that you are and you want to get as much out of this game and now I've started to realise that.
