Probably one of the most intriguing Round 4's of the Six Nations in recent memory gets underway in Rome on Saturday. Both Wales and Italy have EVERYTHING to play for, and for Wales in particular it's do or die stuff, not helped by the crisis in the game back home. England host a French time that looks dangerous but not quite the Grand Slam winning quality of last year. England continue to develop under new Coach Steve Borthwick and "Le Crunch" match will tell us much about what kind of progress they are really making. Lastly, a thriller in Edinburgh awaits despite the promise of foul weather, as Scotland seek to claim their first Triple crown in 33 years and if they upset Ireland then the possibility of Six Nations silverware also suddenly becomes a distinct possibility. For Ireland as the only team left chasing a Grand Slam, there is plenty to play for but also the need to make a statement in this game as a dress rehearsal for their final Pool B encounter in the World Cup against Scotland five months from now. You won't want to miss any of it!!!!!
