I think this year's tournament will be very special because it will take place before the World Cup and the team who will dominate it will have a psychological advantage ahead of October.
All the games will be difficult but I think England remain the favourites. They have the advantage of playing France at Twickenham, after just missing out on the Grand Slam in the past three years. That is why I believe they will be eager to do well this year.
The winner of the clash between France and England should also win the tournament. I would, however, remain wary of Ireland, who have always been difficult to play against, especially on their home ground, even if they totally missed out on their match against France last year. Scotland, Wales and Italy also have a role to play, but they should not be major contenders for the trophy.
I think that the French side are thinking more about the World Cup and are willing to use the tournament for trying as many players as possible to create the best team ahead of Australia.
Regarding the tournament itself, I would like to end by saying that this event has a particular identity, it's different from a World Cup or a tour. The atmosphere is just fantastic. The enthusiasm of spectators is tremendous - many French fans travel to Ireland, the Scottish come to Paris.
This competition has definitely marked the last decade. It is magical.
