CARDIFF Blues head coach Danny Wilson will be well aware of the threat Newport Gwent Dragons pose to his side’s hopes of claiming a top-six finish in the Guinness Pro12.

Wilson’s troops have a league double over the Dragons in their sights tomorrow (2.30pm) at Cardiff Arms Park as they bid for a fourth successive win.

As well as that, the Blues know another victory can work wonders for them in their attempts to qualify for next season’s European Champions Cup.

The Blues must be no lower than sixth after their final game of the campaign away to Edinburgh on May 7, so seeing off the Dragons is imperative if they want to achieve their goal.

But after watching the Dragons upset the odds to get past Gloucester in the Challenge Cup last weekend, Wilson is quite rightly respectful of what their rivals can produce on their day.

“To go to Kingsholm and a packed house in a European quarter-final against a fully-loaded Gloucester and win is quite an achievement and shows what the Dragons are capable of,” he said.

“They certainly haven't been blown away by anybody, they have been in tight battles and have shown they can go away and win.

“It could be a really exciting game between two sides who have picked up two big results, two sides in form moving into what will be a decent afternoon weather-wise and on a surface both teams will want to play on.”

Tomorrow’s clash is the second of three consecutive Pro12 Welsh derbies for both regions – the Blues triumphed 28-22 at the Scarlets last time out while the Dragons came up short against the Ospreys.

“You want to win every single game but derbies have that extra spice to them,” added Wilson.

“We’ve just won one, and it would be an unbelievable achievement to win another two considering we have already won three.

“That would put us into a great position leading into a game against Edinburgh away, which is a tough place to go.

“That would give us the best chance possible (of a top-six finish), we have to win three games but we're taking each game as it comes, especially because the first two are derbies.”
