After just two rounds there are only three teams left with a 100% winning record in the RaboDirect PRO12.
Munster, Scarlets and Ulster are the teams with that distinction but one of those records must go this weekend as Ulster host Munster at Ravenhill on Friday night.
Whilst Munster have the better record in this fixture, Ulster have had the better of their opponents at home, so it really is anyone’s game.
Also on Friday night, reigning champions Ospreys will be looking for their first victory of this campaign. Their adversaries, Glasgow Warriors, are also seeking to shed an unwelcome played two, lost two start to the season.
The final game on Friday takes place in Scotland’s capital city when Edinburgh Rugby take on Italian newcomers Zebre.
The hosts lost their first round encounter against Munster at Murrayfield, despite a hat-trick by Tim Visser, so will be looking for a victory for their fans to cheer.
The round wraps up with three games on Saturday. Connacht kick-off the action at 3pm in the afternoon when current table-toppers Scarlets are the visitors to the Sportsground in Galway, a venue where they last tasted victory in January 2009.
The action then switches to Italy with Benetton Treviso welcoming European champions, Leinster to Stadio Monigo.
Treviso won the first meeting of the two teams in this competition, but the results have gone the way of the Irish province since then.
Last, but by no means least, is the all-Welsh derby between Newport Gwent Dragons and Cardiff Blues at Rodney Parade.
Having led the table after the first round, Dragons slipped up last week to Leinster, and both teams now have a won one lost one record, with both gaining a bonus point in the process.
