Wales head coach Warren Gatland has predicted another "huge" weekend of Six Nations action, beginning with his side's match against France at the Principality Stadium on Friday night.

Wales would climb to the top of the Six Nations table with a victory and could effectively set up a championship showdown against England next month, with a home match against wooden spoon contenders Italy last up.

Gatland's side have not lost to France since their World Cup semi-final defeat in 2011, picking up four successive Six Nations victories since then.

"It's set to be another huge Six Nations weekend. France come to Cardiff unbeaten in the campaign so far, and impressing under Guy [Noves]. We are looking to continue our unbeaten run and will be looking for another step up after the victory over Scotland," Gatland told reporters.

"We have made a couple of changes, one injury-enforced with Luke [Charteris] missing out with a knee injury, but Bradley [Davies] deserves a starting spot as well, so it's a good opportunity for him. We have made two other personnel changes, with Alex and Dan coming into the starting team. They have trained well and will suit the game France will potentially bring as well.

"We initially thought we would have to wait until later in the week to have a final update on injuries, but we know where we are earlier than expected and have told the squad, hence announcing (the team) today as well."

Gatland has also called Alex Cuthbert and flanker Dan Lydiate into his side for Friday's match.
