The Pool 4 game in Dublin starts just five minutes after title holders Leicester Tigers launch their bid for a third successive title in the Courage Gnoll (v Neath).
Last time they were in Donnybrook, Leinster blasted Newport away in the Celtic League and despite the presence of players such as Augustin Pichot, Felipe Contepomi and Daryl Gibson, the Shoguns are unlikely to cause any shocks on the banks of the Dodder. They made a poor start to their league campaign and despite their recent win over Leicester, they won't feature on many people's list as possible Heineken Cup winners. But Leinster will.
They too had a poor start to the season culminating with their failure to qualify for the quarter-final of the Celtic League but their worst performances are behind them and against Newport we were given a glimpse of the type of rugby that so thrilled last season.
