Wasps won the reverse fixture against Viadana by a record scoreline in Italy three months ago as they touched down for an incredible 14 tries in a 90-17 success at the Stadio Comuncale Pierluigi Zaffanella and there was more of the same in Round 6 as they ran riot against the Italians with 10 tries.
The highlight of those was the hat-trick from full back Daly scored in 16 whirlwind first half minutes after flanker Ashley Johnson had got the scoreboard ticking over and making the most of a great driving maul for their first.
Daly went over in the left corner for his first and Wasps' second but Viadana did get off the mark themselves when wing Nicola Sintich capitalised on some sloppy midfield defence.

Once Daly had enjoyed adding two more for his hat-trick and banking the bonus point after just 26 minutes, left wing Tom Varndell joined the party for the fifth and also wrapped things up with the 10th as the Italians were ripped apart.
The inevitable rush of replacements brought a halt to Wasps' scoring and number eight Mirko Monfrino got a second for Viadana to remind Wasps there was still work to do.
Wasps fired back with some sharp tempo and replacements William Helu, Joe Simpson and Taione Vea all cashed in before outside half Joe Carlisle crossed for the ninth to go with his seven conversions.
