London Wasps head coach Dai Young will urge his team to fine-tune their finish skills against opponents making their first home appearance in Europe when the 2003 tournament champions travel to Italy to take on Rugby Mogliano.
Wasps scored three first-half tries in the win over Newport Gwent Dragons but had to wait until deep into the second-half before Joe Simpson finally secured maximum points.
But they will have few excuses for waiting so long against opponents making only their second appearance in the tournament with former Wales prop Young demanding they are more clincial.
Young said: "We left two or three opportunities on the pitch against the Dragons that would have made it a much easier win.
"If one or two stray passes had gone to hand or if our accuracy had been a little bit better there were at least another two or three more tries on the table."
Rugby Mogliano face a daunting task against the two-time Heineken Cup champions.
Flanker Marco Barbini had the honour of scoring the club's first try in Europe against Bayonne last week.
