Cardiff Blues coach Justin Burnell refused to get carried away with his side's superb away from home victory against French outfit Racing Metro in their European Cup opener in Pool Two on the outskirts of Paris on Friday.

The Blues recorded a significant 26-20 away victory, with Tau Filise and young wing Alex Cuthbert both crossing for tries, to put them in pole position for qualification from a Pool which also includes London Irish and Edinburgh.

"We won't be getting carried away with this win," said Burnell.

"We deserved the win and we really fronted up against a formidable Racing Metro side.

"We more than matched them physically and proved we are a good side and I cannot fault the commitment and attitude of any of our players.

"Xavier Rush, Tau Filise, Bradley Davies, Gethin Jenkins and Michael Paterson were all exceptional for us and not many sides will come to France and achieve what we have done here.

"We will enjoy this win but it now makes our next game against London Irish, who we all know are a very good side indeed, more important.

"We have to get something out of that game but this win away in France should give us some real confidence for the rest of our European campaign."
