Munster coach Tony McGahan doesn't believe his side's five point lead at the top of Pool 1 is big enough to start thinking about quarter-final places just yet.
The two-times Heineken Cup winners made it a double over the Scarlets with a 19-13 victory at Thomond Park that made it a perfect four from four. They now lead Pool 1 with 16 points, five clear of the Scarlets.
"We are disappointed with the performance, but that is down to the Scarlets. They came and stopped us at the breakdown, their scrum was much improved, they kicked well and they played with a lot of ambition," said McGahan.
"It was 26 minutes before we had any sustained ball control. We played in fits and starts and, at 6-3, we needed to regroup at half-time.
"We started with real tempo in the second half and got the try, but we didn't kick-on from there. We fell off too many first up tackles in the first half, but once we go that sorted we were ok.
"We recognise we still have a lot of work to do and that this Pool isn't anywhere near finished. We know that and we know it is going down to the wire."
