The power supply for my laptop broke on Tuesday. I may have all the best processors and software installed, but it's not much use if there's no power. The good news is - it saved people having to share the rollercoaster ride of my emotions regarding this evening's match in Paris. Statistically, as has been pointed out, Ireland haven't got a rat's chance. But just as Ireland's 2009 Grand Slam performance counts for little, neither does the slightly one-sided history of Ireland in Paris.

I'm really struggling with this match. The Irish backs have the ability to beat the French in an open game. If France play the same defence as against Scotland, O'Driscoll and D'Arcy will create space and tries will follow.

In the backrow, the inclusion of Ferris is just enough to edge that battle in favour of Green, but to be honest, there is very little in in it.

Up front is a different matter. The French tight five were massive against Scotland - I still don't understand how Nigel Owens did not award at least one penalty try. Ireland did well enough against the Italian pack, but I can't see O'Leary being too comfortable at scrum or ruck. And if last weekend is any indicator, both teams will be targetting the lineout for potential turnover ball.

So when you add it all together, what is going to be the difference? I would suggest that this match will be won or lost by goal-kicking. Surely Ireland have the advantage in that department with the experience of Ronan O'Gara. But O'Gara has been a little inconsistent in recent times. Not to worry - we have Sexton on the bench ... but the we lose experience! IF O'Gara plays well, I think Ireland will be able to cope with the lack of power up front, but if not (and even if Kidney replaces him early), then the superiority of the French pack could leave the undoubted potential of the Irish three-quarters somewhat 'disconnected'.
