The Blues, Ospreys and Scarlets occupy the first three places in the table after victories in week one, with the Dragons the only Welsh side to suffer an opening weekend defeat.
And it doesn’t get any easier for the Dragons who face a tricky trip to Dublin to play Leinster this evening.
The Ospreys will be looking to build on their impressive start when they host Edinburgh on Saturday and the history books are on their side with the visitors not recording a win at the Liberty Stadium in the past two seasons.
The Scarlets travel to Galway to play Connacht and will be looking to overturn their defeat at the Sportsground last season.
And in the final game of the weekend, the Blues welcome Benetton Treviso to South Wales.
