The Western Mail's Gwyn Jones previews a crucial few weeks for Welsh rugby.
"The decisions made and the results achieved during this pivotal period in the calendar defines individuals, coaches, regions and nations. It is a time for those who wish to stand apart to make their move.
"Everyone has something to prove, form turns on its head and only those players and teams that possess the extra will, ability and desire will succeed.
"The region with the best prospect of making the knockout stages are the Blues. The away win in Paris against Racing nudges them into pole position, but they have a very awkward game against London Irish on Saturday afternoon.
"It will be interesting to see if Leigh Halfpenny keeps the kicking duties in the presence of Dan Parks for this match. Halfpenny has a prodigious boot, but his usual role is to take the distance shots at goal.
"Being regular kicker is very different. He has nothing to lose on the efforts from distance and three points is a bonus. But the expectation is very different when you are 30 yards out."
