After next weekend's final round of group games, the best position that Tigers can hope for, I think is 2nd.
Quins (currently 1st) are at home to Castres (9th) on Friday night and will surely win comfortably against a Castres team with little interest in advancing.
Munster (3rd and 1 point behind Tigers) are at home to Wasps (8th) and who'll probably finish in 8th. A Munster bp win?
Bristol (4th and 2 points behind Tigers) are away to Scarlets so a Bristol win can be envisaged.
Tigers (2nd) home to Bordeaux/Bègles (5th and already qualified, but with little chance of getting higher). Bp win, please!
Connacht (6th are away to Stade Français (10th), who have probably abandoned all hope of qualifying. Win for Connacht.
Toulouse (a lowly 7th!) are home to Cardiff, so a winning bp is a cert (especially if Antoine Dupont makes his return from injury, as he's expected to do!)
Group A
We'll begin at the bottom (pardon the expression!)
Glasgow (8th) are at home to La Rochelle (3rd). Glasgow win, no bp?
Montpellier (9th) are at home to Exeter (5th) so I can't see them qualifying.
Clermont (5th) go to Ulster (2nd) so they won't move up the table and could be overtaken by Glasgow.
Sale (6th) are at home to Ospreys, but even a bp win probably won't be enough to move up.
Leinster (3rd) go to Bath (11th) so only one result there!
Racing (1st) are at home to Northampton (10th) so only one result there too!
With the crystal ball out, Tigers (with a bp win, of course!) could play either Glasgow or Clermont on a home & away basis on the weekends of April 8-10 and 15-17, I think.
So we can safely book our tickets for the QFs!!
