O’Sullivan and Gatland’s clash more than a sideshow

After a limited period in the country Gatland also realised that given the quality of backs available to him, he needed an out-and-out open side to complement the running game he was likely to pursue.

After studying the four Welsh regional teams in December, it was clear to him that Martyn Williams still stood head and shoulders over all other contenders. Once again his persuasive powers were seen to best effect in convincing the outstanding Cardiff flanker to come out of retirement. Williams, along with Ronan O’Gara and Vincent Clerc, is already a contender for player of the Six Nations tournament.

The other key decision by Gatland was to appoint Ryan Jones as captain. By omitting World Cup captain Gareth Thomas from the squad, he removed a figure whose strong character had created problems for previous coaches Mike Ruddock and Gareth Jenkins. By overlooking a former captain in Stephen Jones, he sent a clear message that the Llanelli stalwart had a fight on his hands for the out-half slot with the impressive James Hook.

Despite the fact that Ospreys No 8 Jones has struggled with injuries since his remarkable contribution to the 2005 Lions when called in as a replacement, Gatland appointed a free spirit who plays with a smile on his face and is highly respected by his team mates. It confirmed the beginning of a new era.

On Saturday Gatland leads a confident Welsh squad to a venue that, in many respects, will suit their mindset. Many of their squad harbour dark memories of Lansdowne Road where they were on the end of Irish hammerings. The wide expanses of Croke Park hold no inhibitions and in some ways will remind the visitors of the Millennium Stadium.

Having claimed 10 tries in the tournament to date, Ireland know this Welsh team are capable of scoring from anywhere. If they are offered anything like the amount of possession Scotland did 10 days ago, Ireland will be in trouble.

The biggest problem for Wales in recent seasons has stemmed from the vulnerability of their front five. While the scrum has improved somewhat, their line-out is still suspect and the decision by Gatland to make three changes in the pack that faced Italy suggests that this remains an area of concern.

The return of Paul O’Connell to the Irish forward unit is a timely boost even if Mick O’Driscoll has done nothing wrong and is sure to see some game time. Ireland will seek to turn this contest into a dogfight up front.

This game has the potential to light up the championship and generate the type of atmosphere that electrified Croke Park last year, but was conspicuously lacking against Italy and Scotland. With Ireland travelling to Twickenham the following week, the result will make or break the season.

For Gatland, more than O’Sullivan, this one is personal — but whichever emerges victorious will derive tremendous satisfaction. The competitive nature that defines both men makes that a certainty.
