All change for 2020: What can we expect from this year's Six Nations?

One of rugby's greatest championships is almost here.

The northern hemisphere's best teams are set to do battle once again in the latest instalment of the Six Nations.

It is set to be one of the most intriguing tournaments in years as the teams make a variety of changes following the Rugby World Cup.

Reigning champions Wales are one of four teams to have a new head coach.

Four teams will also have new leaders on the pitch - with first-time captains leading out Italy, Ireland, Scotland and France – Luca Bigi, Johnny Sexton, Stuart Hogg and Charles Ollivon.

Wales' women side will also be under new management - coach Chris Horsman will be hoping his side can continue their good form from the Autumn which saw wins over both Ireland and Scotland.

  • A new era of Wayne's world?

Wales captain Alun Wyn Jones has warned it will be a bumpy road following Warren Gatland's departure.

Pivac confirmed that 18-year-old Gloucester wing Louis Rees-Zammit is set to be available for Wales' opening match against Italy.

The teenager went off injured during his side's Champions Cup defeat against Toulouse on Sunday.

But Liam Williams, who has not played since he injured his ankle at the World Cup, is not due to return until Wales' second fixture with Ireland.
