All four Irish teams have already qualified for the last 16.
Connacht joined Munster and Ulster in securing qualifying with the Toulouse – Cardiff cancellation, which prevented the Western Province from being knocked out of the top eight in Pool B, regardless of what happens in their encounter with Stade Francais on Sunday.
Meanwhile, Leinster cleared the case to Bath in Saturday’s early kick-off.
In order for Munster to finish in the top two of Pool B, they need to improve on the result of Leicester Tigers or Harlequins. Johann van Graan’s side welcome a rejuvenated Wasps to Thomond Park, with the England side bouncing on recent wins against Leicester and Toulouse after seeing their injury problems ease.

Connacht fans traveling to Paris can expect a dry afternoon with temperatures of 3-5C. It is expected to be quite calm on Sunday afternoon in Limerick, where wasps receive in Munster, with an expected dry day and temperatures of 8-9C.
After last week’s painful defeat to Leicester at the Sportsground, Connacht hopes to return in style in Paris.
If they can produce anything close to a repeat of their previous meeting with Stade at the Sportsground in December, they should be well on their way to improving their seed for the knockout stage.
Andy Friend’s side were 39-9 winners when the sides met in the first round, with Stade playing a similar match to Connacht in recent weeks against Leicester and Munster.
Another point of optimism for Connacht is the 4G pitch at Stade Jean-Bouin, which should provide them with an ideal platform to play the running game for which they are best suited.
The French side won 35 of their 36 home matches in the group stage of the Heineken Champions Cup, their only defeat to Harlequins in 2008/09 (10-15).
Meanwhile, Connacht have lost their last seven away games in the league, but their last three defeats have come by a margin of less than seven points.
Stade looks much stronger than their December lineup, with Ngani Laumape and Clement Castets adding bulk to their squad, while Connacht is without Finlay Bealham, Ultan Dillane, Kieran Marmion and Bundee Aki.

Six weeks ago it looked as if Munster’s season had come to life when their patched-up team smashed up Wasps in Coventry, but while they’ve won three of their four games since then, their performances have been inconclusive.
They scored four tries that afternoon, but have only crossed the line five times in four games since then.
Despite their performances, a place in the quarter-finals has already been secured, only their placement has yet to be determined.
Wasps have recovered from that defeat in December and with the help of some key players returning from injury, have beaten Toulouse and Leicester Tigers in recent weeks.
However, they will have to be without Jacob Umaga for the trip to Limerick after his red card against the defending champions a week ago.
Sunday’s game will be the sixth between the sides in this competition, with Munster leading the rivalry three-on-two.
Munster: Mike Haley; Andrew Conway, Chris Farrell, Rory Scannell, Keith Earls; Ben Healy, Conor Murray; Dave Kilcoyne, Diarmuid Barron, Stephen Archer; Jean Kleyn, Tadhg Beirne; Peter O’Mahony (c), Jack O’Donoghue, Gavin Coombes.
substitutions: Scott Buckley, Jeremy Loughman, John Ryan, Fineen Wycherley, John Hodnett, Craig Casey, Jack Crowley, Simon Zebo.
