But, however, he is not thinking about that possibility for the time being.
The former Great Britain rugby league star signed a new deal over the weekend to remain with the Welsh Rugby Union for at least another four years, in a role that also allows him to work for an Aviva Premiership club on a part-time basis.
The new deal ended any chance of the highly-rated 45-year-old, who stepped down from his post at Wasps two weeks ago, joining England's coaching team before the 2015 World Cup, but he has not ruled out the idea in the long term.
He wrote in his column in the Guardian: "The Ts have been crossed and the Is dotted, so for the next four years, until at least the 2015 World Cup in England, I'll be with Wales. Adds a bit of spice to life doesn't it? But there are bound to be those who say: 'Why not England?' Well, the simple answer is that they didn't ask.
"Some time, a bit further down the line, there may come a time when I get to wear the red rose. It is something I would enjoy because, after all, I'm English and representing your country is what you aspire to. However, at the moment I don't want to talk about England.
"I did get a few other calls once it became known that I was a free agent but since the day I left their employ, Wales and the WRU chief executive Roger Lewis have been perfectly professional about getting me back on board.
"Even before we left New Zealand and the World Cup we had spoken and when the Wasps situation became apparent that was taken into consideration as well."
