We are in a World Cup year. The Welsh players given a chance this afternoon by Warren Gatland have got to take it and have a great game as they may not get many more chances to stake a claim.

As for Tonga, they ran in seven tries last weekend against the French Barbarians and another big performance here will certainly make their World Cup pool rivals England and France stand up and take notice.

Dan Biggar will start at fly-half for Wales against Tonga, as coach Warren Gatland makes 14 changes for Saturday's autumn international in Cardiff.

Fellow British and Irish Lion Liam Williams is named on the wing, with Steff Evans on the other flank.

Leicester's Jonah Holmes makes his debut at full-back.

Seb Davies starts at number eight, with Cardiff Blues team-mate Ellis Jenkins, who captains Wales, and Dragons' Aaron Wainwright completing the back row.

Davies was not part of the original squad but will win his second cap against the Tongans at the Principality Stadium.

Wales: Jonah Holmes; Liam Williams, Tyler Morgan, Owen Watkin, Steff Evans; Dan Biggar, Tomos Williams; Wyn Jones, Elliot Dee, Leon Brown, Jake Ball, Adam Beard, Aaron Wainwright, Ellis Jenkins (capt), Seb Davies.

Replacements: Ryan Elias, Rob Evans, Tomas Francis, Cory Hill, Ross Moriarty, Aled Davies, Rhys Patchell, Josh Adams.

Now Wales face a side they have never lost to - Tonga.

Warren Gatland has rung the changes for the visit of the Pacific Islanders, who head into the Test in good form and looking to spoil the party at the Principality Stadium.

Yes, Wales will still be riding high after beating Australia for the first time since 2008 thanks to Dan Biggar's late penalty last Saturday.

Leigh Halfpenny had edged the hosts into a 6-3 lead, but Matt To'omua drew Australia level with five minutes left.

However, just two minutes later, Biggar struck the decisive blow.
