Helu and Thompson star for Wasps

Wasps showed their ruthless streak with a staggering 14 tries at Stadio Pierluigi Zaffanella that included hat-tricks for both William Helu and Guy Thompson.

Joe Carlisle converted 10 as Wasps enjoyed their biggest win.

Wasps led 56-3 at half-time, Helu kicking off the rout in the 10th minute after Viadana's Daniel Yakopo was binned.

The visitors' scrum then claimed a penalty try followed by a Kearnan Myall score three minutes later.

Thompson notched his first on 23 minutes and Thomas Bell followed before Helu crossed twice in the space of three minutes.

Simon McIntyre touched down for Wasps' eighth try of the half, while Viadana mustered a response through Andrea Barbieri before half-time.

Flanker Thompson then completed his hat-trick seven minutes into the second half, while a brace of tries by Jack Winter-Moates saw Wasps surpass their previous highest tally in Europe - 77 points against Toulouse back in 1997.

Charlie Hayter and Joe Simpson then rounded off an historic win with further tries in the final 13 minutes.
