Martyn Williams reckons there is more to come from Cardiff Blues ahead of their monster clash with Gloucester this weekend. 

The Wales flanker saw his team-mates romp to a 56-20 win over Calvisano in round one. 

Gloucester also kicked off with a win over Biarritz but face a titantic Anglo-Welsh tie at the Millennium Stadium. 

The sides have played three times before with the Cherry and Whites boosting a 100 per cent record.
