Harlequins winger Tom Williams is not underestimating Heineken Cup Pool opponents Zebre when they meet at Stadio XXV Aprile this weekend.
The Premiership pace-setters missed out on the knockouts of last season's European competition but are four points clear in Pool 3 this campaign.
However, memories of losing to Connacht in Galway remain in the back on Quins players' minds and Williams is determined to not slip.
"We underachieved in the Heineken Cup last season," he told ercrugby.com.
"Connacht did brilliantly to beat us in the final Pool game and that cost us so we know we can't afford to take any side lightly.
"Zebre have only played a few games, they've played twice in the Heineken Cup and then they've had their league fixtures in the PRO12, so we've done as much research as we can.
"They have pushed other teams close and the two examples that come to mind are against Ulster at home when they only narrowly lost, while they gave Munster a fright at Thomond Park.
"They look to be an exciting team. They've got some brilliant backs and some class players in the forwards.
"They have a couple of lads with some real pace out wide while the nine and 10 look lively so we've got to stay alert. However, we always pay due respect to our opponents.
"We're doing well in all the competitions - we are top of the Premiership and looking good in the Heineken Cup - but it is a sign of how far we have come and developed as a team that we are still not satisfied."
