It's set to be one of the most hotly contested Six Nations in years with five teams looking like they'll be able to put together a championship winning charge.
The autumn saw both Ireland and France beat the All Blacks while England beat world champions South Africa at Twickenham with both Scotland and Wales beating Australia.
Italy have also been putting in creditable performances with a young squad but they still appear to be a level below the competition for this year's tournament.
Yesterday it was confirmed that Elliot Daly, George Ford and Nick Isiekwe would be replacing Owen Farrell, Courtney Lawes and Jonny May following injury concerns for Eddie Jones.
This means that the squad list is now updated to include the additional names with the injured players likely to return later in the tournament
