Jonathan Davies is determined to prove Wales ’ doubters wrong in the final weekend of the RBS 6 Nations and plans to celebrate the championship with a plastic cup after a silverware snub . With trophies being sent to Twickenham and Murrayfield , Wales will return home from Rome empty handed even if they go on to win the three-horse race for the title . Warren Gatland ’ s side need a thumping victory over Italy to overturn their points deficit on England and Ireland and — despite the Kiwi keeping his counsel about the scenario — there is understood to be some disappointment about the organisers ’ trophy decision . Wales centre Jonathan Davies is tackled by Ireland lock Paul O'Connell ( left ) and tighthead Mike Ross . ‘ I ’ m sure we ’ ll find a trophy somewhere , like a plastic cup or something , ’ said Davies . ‘ Obviously people are doubting us and they don ’ t think we ’ re going to be involved . But we just worry about ourselves , concentrate on ourselves , and will put a performance together that hopefully means we can get the cup on Sunday. ’ Welsh hopes of a landslide victory could hinge on the fitness of Italy No 8 Sergio Parisse , who has a ‘ 30-40 per cent chance ’ of being fit . Italy have delayed their team announcement by 24 hours to give him time to recover , but Davies says Wales will not change their approach even if the 31-year-old is ruled out . Scott Williams is congratulated by Davies and Dan Biggar following his crucial try against Ireland . ‘ We can ’ t fall into that trap , ’ said Davies . ‘ If you do , the pressure seems to come on you rather than the opposition . ‘ Italy have some key injuries with the captain maybe being out , and after the disappointment of France , they ’ ll have doubt in their minds . ‘ It ’ s about us going out there and stamping our authority . It ’ s about sealing that doubt and building from there. ’ While Italy are struggling for form , Wales are still building momentum after their victory over Ireland . A fine defensive display kept the championship race alive , however Davies knows his side must add more cutting edge in attack . Warren Gatland 's side are in a three-horse race for the Six Nations title that will be decided on Saturday . ‘ Looking back on the Ireland game , we probably left two or three scoring opportunities out there , ’ said Davies . ‘ This week we ’ re going to have to take all our chances . ‘ As a back line we haven ’ t fired as we ’ d have wanted to . The forwards have worked tirelessly all campaign for us and there ’ s pressure on the backs now to take opportunities. ’ If Wales can rack up the points , the pressure will move on to Ireland and England , who are up second and third against Scotland and France in the afternoon of staggered fixtures . Davies and his countrymen will watch events unfold from Rome and he plans to cheer on his French clubmates from Clermont Auvergne . Italy 's captain and talisman Sergio Parisse faces a race to fit for the visit of Wales on Saturday . ‘ France can be amazing at times , ’ said Davies . ‘ Hopefully , they can turn up and do a job . They ’ ve done it in the past. ’ Aside from two injury-enforced changes in the front row , Gatland has kept faith with the starting XV who beat Ireland . Scott Williams scored the decisive try and the centre was on Wednesday among the latest batch of players — along with Alun-Wyn Jones , Dan Lydiate and Gareth Anscombe — to sign a dual contract with the WRU and their region . ‘ Alun-Wyn , Dan , Scott and Gareth represent a cross-section of experience . Each one of them is a player of proven talent , ’ said Gatland .
