Liverpool defender Virgil van Dijk insists that his side shouldn't be complacent by their "lucky" win away at Porto last season, ahead of the second leg of the Champions League quarter final on Wednesday.
The Merseyside club will take a two-goal advantage to the Estádio do Dragão, where they won 5-0 in last season's clash, as they look to set up a semi-final match against Barcelona in Europe's elite competition.
But Van Dijk has played down the chances of Liverpool holding out for a clean sheet in Portugal, claiming that the Reds will have to get on the scoresheet to secure a second appearance in the semi-finals in as many years.
