Davies warns of hard work ahead
Cardiff Blues director of rugby Phil Davies has warned his side they must raise their game to a new level if they are to complete the Heineken Cup double over Glasgow.
The Blues head north to face the Warriors at Scotstoun having emerged 29-20 winners at the Arms Park when the sides met last weekend.
From the ruins of their heavy defeat at Exeter in the opening round of Pool Two fixtures, Cardiff have risen to lie second in the standings after victories over defending champions Toulon and Glasgow, and trail the French club by just a point.
Another win on Friday would keep the Welsh region firmly in the qualification mix, but would all but end Glasgow's hopes.
And Davies believes that means his side have to raise their game.
"We were pleased with the motivation and spirit we showed last week," the former Scarlets and Leeds boss told the club website.
"We have been getting better all year and at the moment the performance levels are growing.
"We will need to work even harder up in Scotland. We need to go up a level physically and tactically, be more accurate with the ball.
"Last week was about desire and performance, this week we need to extract even more from the players.
"I expect Glasgow to play like men possessed. We looked to play a certain way last week against them and executed it.
"But we know how good they can be and have had some terrific games up there. Friday will be no different.
"The team that controls the ball in the opposition attacking third will be hard to beat.
"It's a tough game because they will have been disappointed by last week, but we need to build on what we have achieved in this competition."
Davies has made just one change from the win in Cardiff, with Rhys Patchell moved into the centre due to Dafydd Hewitt's shoulder injury and Gareth Davies starting at fly-half.
Glasgow hand a first start to Fijian lock Leone Nakarawa, while Tommy Seymour returns from injury.
In Pool 1 the Ospreys will look to record their first win in the competition this season as they host Castres at the Liberty Stadium.
Many had tipped Steve Tandy's side as the most likely Welsh region to launch a strong Heineken Cup campaign, but they are as good as out of the tournament after three straight defeats.
As with last weekend's defeat in France, it will be a young Ospreys side, with 20-year-old Sam Davies making his Heineken Cup debut at full-back.
Sam Lewis joins Justin Tipuric and captain Ryan Jones in the back row while Ian Evans comes in for the rested Alun Wyn Jones at lock.
In Pool One of the Amlin Challenge Cup, leaders Sale will look to gain revenge for their defeat in France as they host Oyonnax at the AJ Bell Stadium.
The Sharks lead Biarritz by a single point and will be looking to tee up a potentially decisive meeting with the Basque side next month.
