It all adds up to the group honours now looking set to be a straight fight between these two former European champions

Tuilagi - in outstanding try-scoring and try-providing form in England's victory over New Zealand eight days earlier - got into the try scoring act for his club with a 24th minute effort after the Tigers had opened their account with a penalty try awarded by Irish referee George Clancy.

The No 7s then took centre stage, Julian Salvi crossing for the Tigers only for opposite number Dean Budd to immediately open Treviso's account in the 31st minute with a try converted by Alberto De Bernardo.

Salvi's response was to go over for his second try and enable the Tigers to bank the bonus point before the break, outside half George Ford weighing in with three conversions.

Treviso reminded the Tigers they still had some work to do with Lorenzo Cittadini crossing for their second try but when Simone Favaro was yellow carded - Treviso's fifth sin binning of this season's tournament - the home side made their extra man count with Matt Smith getting their fifth try.

Treviso could sniff the chance of a try bonus point when Christian Loamanu got their third but that came to nothing as the Tigers rode it out.
