The tie of the weekend sees unbeaten Cardiff Blues travel to Gloucester for a crunch clash in Pool Six. 

The Blues have won all four opening fixtures and a fifth straight win will put the Welsh region into the last eight. Dai Young’s men will make the short trip in confident mood after beating Biarritz in France last time out.

But Gloucester lie just four points behind and will hope home support at Kingsholm will work to their advantage.
