CERI Sweeney vows to put last week's Heineken Cup horror show behind him and help steer Newport Gwent Dragons to victory second time around against Edinburgh at Murrrayfield on Sunday.

Wales outside half Sweeney and the Dragons came in for a fair amount of stick last week for getting their tactics wrong, for failing to adopt a kicking game in the dreadful conditions and for letting Newcastle off the hook.

That meant the Dragons slipped to only their second defeat at Rodney Parade and are now staring at a shock early exit from the competition after just two games -- unless they beat the leading Scottish team.

Sweeney (pictured above) acknowledged his and the team's failings last week and gives an assurance they won't be repeated on Sunday.

"How can you play in conditions like that?" he asked. "We tried, but we played it wrong. We got into positions, but we got too rash and tried to move it but knocked the ball on.

"We played some pretty good stuff in the first half. We could have kicked a bit more, but the wind suddenly changed and it was against us when we thought we had it.

"I'm getting used to criticism, maybe some of it was justified. But we've looked at the video with Chris (coach Chris Anderson) and I could have kicked it a bit more. But they are things which we can put right.

"The weather did play a massive part last week and we just couldn't handle the conditions.

"Now we've got to win on Sunday, we have worked really hard in training this week and we have put ourselves into positions where we can take advantage.

"We will be better prepared if the conditions are similar though I don't think it's going to be so bad up there."

Sweeney refuses to believe it might be easier because the Dragons are facing a fellow Celtic League team this time and beat them at Meadowbank Stadium last season.

"Edinburgh have got a pretty sharp line-out, they've got a lot of internationals in their side and a few backs who can break defences," he said.

"They played well in Europe last year (they reached the quarter-finals) and they did well in Perpignan last week. They've got some quality players.

"But every team that plays in Europe is a great side and things can be settled on one mistake. We've been playing good rugby and we haven't even thought about defeat.

"I certainly hope last week was a blip. Everything is based on Europe now and I hope we can bounce back.

"If we cut out the mistakes we can come up with a win."
