NEWPORT wing Matt Mostyn (pictured) warns star-studded Leinster that the best is yet to come.

Mostyn returns to Ireland tomorrow for a big Heineken Cup clash, and while he wants to add to his five caps he is putting his international ambitions on the back burner in the interests of the team.

Leinster are out to extend their winning run this season into double figures, but Mostyn says if Newport click the Irishmen could be in trouble. "The difficulty is being able to go away and win, but we've done that and the way the team has gelled to a different style meaning it's exciting times for us," said Mostyn. "And we haven't played at our best yet, maybe for 15 minutes against Newcastle and Toulouse so this is the time to do it. "If you sat down with the players they would say that not everyone is at the top of his game. But if we all click and hit some real form we're going to be a dangerous side. "Leinster are a difficult side to play against and they are playing an exciting style under Matt Williams who believes in keeping it wide and playing attractive rugby. "It would be great to go over there and win, we'll have to be at our best." Australian-born Mostyn, who qualifies for Ireland through his grandparents, says current form there means players are queuing up for places.

But his head-to-head with in-form Denis Hickey will decide whether there is any international future for him.

"When I first came in from Australia I was happy with the way I was playing and I scored three tries in a friendly against Argentina," he said.

"Then I had injuries and I was not at my best. We lost against Argentina in the World Cup which was a bit of a disaster.

"There was a sweep-out and I was part of that, but I've been playing pretty consistently again (22 tries last season, three this) so I've got to try to pull out a few big ones and get the nod.

"I've played a couple of times against Denis. He's in an in-form Irish side who are playing with a lot of confidence and he's reflecting that.

"He's a busy player, but I've got to concentrate on playing well myself. Ireland are on the crest of a wave and I'd love to be involved. I've got to put my hand up and hopefully get a chance."

Mostyn will be re-united with some Irish teammates tomorrow and even with an Australian who was at his wedding Down Under in the summer.

"It's a big game and I've been thinking about it ever since the draw was made," he said. "Nathan Spooner (Leinster's Australian outside half) was at my wedding so there are strong connections.

"You can make too much of it all, but there's a lot of motivation to get stuck into the Irish boys."
