The Ospreys will welcome Saracens to the Liberty Stadium on Saturday 13th January 2018 (7.45pm KO) for a fixture that is set to define the European Rugby Champions Cup campaign for both teams.
The sides experienced contrasting fortunes in the December double headers, the Ospreys running in 10 tries to secure two bonus point wins over Northampton Saints while Saracens suffered back to back losses against Clermont Auvergne.
As a result the Ospreys leapfrogged the reigning European champions to move into second place in Pool 2 and know that victory at the Liberty Stadium in Round 5 can end Saracens hopes of progressing and keep their own prospects very much alive going into the final round.
Round 6 sees the Ospreys head to the Massif Central to face French champions Clermont Auvergne on Saturday 20th January at 4.15pm local time.
Tickets for both of these matches are on sale now at the Liberty Stadium Ticket Office and online at www.ospreysrugby.com/buytickets, with Saracens tickets starting at just £15 for adults.
