A massive challenge that is how returning Wales lock Ian Gough describes Newports Celtic League quarter-final against Leinster at Donnybrook tonight.

Gough makes his first start for Newport since Mays Principality Cup final when he badly damaged a shoulder.

He has made three appearances as a replacement, played once for Wales A and earned his place back in the Welsh team against Tonga and Australia.

Its been a long time coming, admitted Gough. Mike Voyle has been playing well and its great to start now.

Its created a problem for the coach, but I hope to prove a point. Sunday was a good run-out, it was tough and very physical before they brought me off for fresh legs.

Physically and mentally Im back, Im pretty much up there, though theres always room for improvement. Theres always more to come, especially with a new coach with different ideas.

Leinster have beaten us twice, but theyve been close games.

Well see whats between us now. Theyre a great team and its going to take a massive effort. We know weve got a mountain to climb.

Theyre unbeaten and theyve got the cream of Irish rugby in their team, so if we win thatll make it all the better.

Gough believes Newport are in with a shout.

Its always a bit harder to win away, but weve done it at Bridgend, Neath and Newcastle, so people can win away, he said.

They came here and won and this is a formidable place with passionate support.

Theyve had the breaks, and if we play as well as we can we have a chance.

Gough goes head-to-head with Ireland and British Lions lock Malcolm OKelly for the first time.

Ive played against him for Wales, but I was front jumper and I havent had the opportunity of playing him five against five, he said.

Hes a quality player, hes not a British Lion for nothing.

But Gough remains optimistic. Weve been relaxed in training and were looking forward to it, he said.

And for local lads like Dale Burn its a big opportunity. Its one of the biggest stages to play on.
