WALES flanker Colin Charvis says the squad are united in aiming for a big performance against Argentina at the Millennium Stadium on Saturday.

Charvis and Wales coach Graham Henry were critical of each other after the British Lions tour of Australia and Charvis followed up with one of his weakest performances for his country in the hammering by Ireland.

Problems over contracts have also been well documented and there have been suggestions in at least one newspaper this week of a split in the Welsh camp.

But Charvis said: "I've had other reporters mention there are splits in the camp over things to do with contracts.

"But as a player who has been involved in the last two games and now this game, I am not aware of any split, any divide or any problems."

He added: "I'm quite comfortable with the way I'm playing. Obviously Graham has shown a bit of confidence in me by keeping me in the team.

"I've just got to keep concentrating on my own game and see how I can improve. "I think you are judged on each performance, whether it is on the back of a defeat by Ireland or at any other point., and that's how selection should be.

"The expectations within the squad are for a much better, much stronger performance against Argentina.

"If we can do very well individually then the team will come together. If we all provide, then hopefully we will get a victory."

Charvis admits the public reaction after the Ireland game was hard to take, though disappointment was natural.

"I think it was a harsh reaction, very harsh indeed. None of us chose to go out and play so badly. It's one of those things that happens," he said.

"It's difficult to justify it though I can understand there was a lot of anger there. But we were feeling low as well. We were disappointed with ourselves as a squad.

"If they want to take it out on the team, so be it. It's up to us though just to try and build for our next game."

Wales have beaten Argentina four times in recent season, but Charvis is not sure whether those results will have any bearing on tomorrow's game.

"You could say we could be overly confident or they could be desperate for revenge," he said.

"They could look at the climate of Welsh rugby and think this is their chance to turn us over.

"They could look at their result against Wales A and think this is a springboard to beat the senior squad.

"I think it's just going to be a case of who plays the better rugby on the day.

"They looked very good against our A side at Pontypridd in midweek and we need to be on the ball and pull off a victory, which we need as a squad after a very disappointing result against Ireland."
