Pool rivals fail to make splash in early defeats
Munster were the only team in Pool 6 of the Heineken Cup to win at the weekend.
Rob Penney's men, of course, defeated an Edinburgh side they will face next month in the premier competition when they began their RaboDirect Pro12 campaign with an impressive bonus-point 34-23 win over the Scots.
Edinburgh will hope to bounce back this evening when they entertain a Dragons side who opened their campaign with a surprise 15-8 victory over an Ulster side who started last year's Pro12 with 11 straight wins.
French club Perpignan, who defeated an understrength Grenoble side at home in midweek, sent a second-string outfit to Paris to play Jonathan Sexton's Racing Metro 92 and came away with a losing bonus point.
They went down 19-16 after a gutsy performance and came close to snatching a draw but James Hook's late penalty from halfway was just short.
Gloucester were surprisingly turned over 22-16 at home by Sale Sharks in the English premiership, with two TMO decisions going against the Cherry and Whites.
They now face a battle to a avoid a second successive defeat when they travel to play a Saracens side who opened their campaign with an impressive 42-20 victory against London Irish.
