New Wales skipper Dan Biggar expects "one or two cross words" with his friend and rival Johnny Sexton during the Six Nations opener at the Aviva Stadium on February 5.
Biggar, who got close to Ireland captain Sexton through Lions duty, admits an opening trip to Dublin is a tough one for the injury-hit reigning champions but claims there is a "bit of a swagger" among Wayne Pivac's players heading into the tournament.
Sexton said earlier this week that he was looking forward to going up against Biggar in his new role, which he has taken on in the absence of the injured Alun Wyn Jones.
