Glasgow v Scarlets
The reigning GUINNESS PRO12 champions have picked a strong side for their second European Champions Cup pool fixture, with names like Stuart Hogg, Alex Dunbar, Tommy Seymour and Jonny Gray all starting.
Glasgow's last outing came on the November 27 when they secured a 13-6 victory over Benetton Treviso, with last week's fixture against Leinster having been postponed.
GUINNESS PRO12 leaders Scarlets have not been able to transfer their league form into their European campaign as of yet, having lost both their Champions Cup pool fixtures so far.
Scrum-half Gareth Davies returns to the starting line-up after not featuring since the loss to Racing 92 on November 21, after impressing for Wales during this year's Rugby World Cup.

Having lost against Exeter in their opening Champions Cup fixture, Raphael Ibanez has made drastic changes to his starting line-up, with flanker Hugh Chalmers the only man to retain his starting berth from that loss.
Pool 2 toppers Ospreys look to get back to winning ways in European rugby after losing away to Clermont Auvergne on November 22, scoring four tries in the process to earn two bonus points.

CHALLENGE CUP
Newport Gwent Dragons v Pau

Pau lost their only game of the Challenge Cup this year to Sale Sharks after the home fixture against Castres was cancelled following the Paris attacks.
With New Zealanders Colin Slade and Conrad Smith incoming, Pau will fancy their chances of making a name for themselves in European rugby this season.
Coach Simon Mannix will be able to count on experienced tighthead Euan Murray to shore up the French side's scrum.

After six games played without yet registering a win in the Premiership, Tom Coventry's side sit at the bottom of the table.
