Who would have thought the Express could come up with such a perceptive and positive article Sparkle!
I understand why a showbiz/tv producer type might think Andy could regret missing out on the show, but I'm surprised a serious athlete can't see that Andy is far more likely to regret not putting his all into training. Regardless of how well Andy does in Australia, the knowledge that he's done everything he can to get back to full fitness will satisfy him.
I think it shows Lineker is out of touch with what it takes to participate at the top level, in individual sports. I can see there might be a different attitude when you play as part of a team, where you can still play, safe in the knowledge you can be substituted if you get weary.
Andy will have plenty of time to turn up when he's retired.
