Leigh Halfpenny reckons Wales can roll back the clock and repeat their feats of 2013 this year by winning the Six Nations title, despite losing to Ireland in their last encounter.

SPECIAL REPORT BY WILL KELLEHER: No player has run out in a Test match at Wales' Principality Stadium having been born after the ground was built. Rees-Zammit could change that fact.

Les Bleus are unbeaten in the tournament so far after wins against England and Italy at home but Wales lock Jake Ball has warned they are ready to make the most of a 'hostile' atmosphere in Cardiff.

Wayne Pivac believes his wise Wales will overcome French flair on Saturday in the Six Nations having picked the most experienced line-up to grace the championship.

If on Saturday the tide has turned against Wales, the French are flooding through in attack and causing chaos it will be the old men of the sea who guide those in red to calmer waters.

WILL KELLEHER AT PRINCIPALITY STADIUM: And so the fortress has fallen. After 10 years of being out-gunned in Cardiff, the French revolution is well and truly alive.

As Sportsmail reported last month, full back Liam Williams has made a swift departure from under-fire European and English champions Saracens after their salary cap disaster.

Liam Williams, Josh Navidi and George North all set to be fit for selection for boss Wayne Pivac as Wales were handed a triple boost before taking on England at Twickenham on March 7.

EXCLUSIVE BY WILL KELLEHER: Welsh victories at Twickenham are rare but much-celebrated occasions. Sportsmail spoke to those involved in the most recent triumphs.

Wales' oracle has spoken and delivered doses of reality to his nation. Alun Wyn Jones does not talk much, but when he does it is worth listening to the totemic and decorated captain.

Wales will be hopeful Dan Biggar does not spark a backline injury crisis ahead of their Six Nations match against England after going off early for Northampton on Saturday against Saracens.

SIR CLIVE WOODWARD: Mark Wilson and Anthony Watson will make their first England appearances since the World Cup final against Wales on Saturday.

The 21-13 defeat killed off English hopes of a Grand Slam, before Warren Gatland rubbed salt in the wounds by questioning their big-game ability.

Alun Wyn Jones moved to ease fears that Dan Biggar is not fit for Wales' trip to Twickenham by saying he will play against England on Saturday despite suffering a knee injury for Northampton.

Wales captain Alun Wyn Jones and his team-mates set out to antagonise Sinckler at the Principality Stadium and the England prop was replaced soon after losing his composure in last year's meeting.

NIK SIMON: England face Wales in a mouth-watering Six Nations clash seeking revenge after suffering defeat in Cardiff a year ago.

Josh Navidi once turned All Blacks heads and has now been backed to leave England blue too at Twickenham. He had hamstring trouble but is now fit to start on Saturday.

CHRIS FOY: Twickenham will be a sanitised zone but the health and safety initiatives will not extend to the field of play, as England seek to end Six Nations campaign with a vengeance.

CHRIS FOY AT TWICKENHAM: Wales didn't even bother to try to antagonise Kyle Sinckler again this time. He has matured a lot in the space of a year, as he proved on Saturday

MIKE BROWN: Players love seeing what grenades Eddie Jones throws during his press conferences. Sometimes they will be watching on social media to see what he comes out with.

SIR CLIVE WOODWARD: It might have been a little subdued before the match but we should have known England and Wales would provide some action to perk us up. The 33-30 win for England was all action.

England could find themselves in treble trouble after Eddie Jones slammed the 'rubbish' refereeing at Twickenham and Joe Marler grabbed Wales captain Alun Wyn Jones by his genitals.
