Yes, Australia looks impressive.
I shall support Wales of course, (as I often do). I like that little team; I have seen her improve over the past few years but, like you, I think they will need a bit of luck!
The French have always enjoyed Wales-France rugby matches, it has always been The match of the tournament that was important, particularly in the days of JPR (who left a very nice scar on my Husband's leg !) , Gareth Edwards, and our own Albanadejo, the Spanghero brothers etc... A different rugby in those days!
~Saint Andre is viewed with mixed feelings I think - So far, I think he has had strange choice in his players perhaps in order to protect the better, more experienced ones from a bad injury this early in the competition - but luckily he changed a number of players around for the 2nd half of France-Roumania, otherwise we would have lost!
I am quite concerned about Saturday, (as I said, the Irish never let go) , but even if we did win, we would probably end up by meeting Argentina in the quarter finals - and they can be dangerous too!
