Nah mate! Don't start talking about retirement with Punter.
He's already gotten out of T20 cricket to further his focus and chances of longevity. He just hasn't gotten off yet this series. The media gave him a crap time and he gave them two middle fingers in response when he set off in Hobart. That was just sensational! Punter in particular cops a tough time from the media.
I never lose doubt in Punter's abilities, he'll get a solid innings in there soon enough.
Retire from ODI's and focus on Tests? Hah.
When he does it? When he isn't enjoying his cricket anymore and feels he is letting the team down, that is what he's indicated many times.
But after the way he lead us in the Champions Trophy and India, don't see it happening, personally wouldn't want it to happen. I have watched him from his ODI and Test debuts and it will be a sad day when I see a career of a great bloke and epic cricketer I've watched so intently come to an end.
