This week sees the teams rounding up the pool matches of the Heineken Cup in the six round of matches, before we move to the second round of the competition.
Last week we already saw reigning champions Toulon with Ulster, Toulouse, Clermont, Munster and Leicester Tigers booking their places in the last eight, with Toulon, Clermont and Muster confirmed already as pool winners.
Only the top four raked clubs at the end of the pool stages gets to host one of the quarterfinals in April, so this weekend will have its share of tension for the teams. Ulster are on top with 22 points followed by Toulon with 20 and Toulouse and Clermont both on 19, but come Sunday all that would have change.
We also have a fight going for three spots in the Challenge Cup for the third, fourth and fifth best pool runners-up.
The clash of two former champions, Leicester and Ulster, on Saturday is arguably the match of the round. Confident in the knowledge that qualification is assured, the Welford Road stage could be set for a feast of attacking as both clubs chase a top-four seeding.
