After a round of games that saw four home wins, with two of those victors also picking up try bonus points, the same four teams Ospreys, Leinster, Munster and Glasgow Warriors still occupy the Pro12 play-off zone.

Elsewhere on the table Scarlets were the biggest movers last week with their 22-12 win over Welsh rivals Newport Gwent Dragons lifting them two places to sixth. The Llanelli based outfit will look to continue their winning ways in Ulster on Friday night.

Also on Friday another Irish v Welsh fixture takes place at the RDS in Dublin when Leinster host Cardiff Blues. Leinster only lag behind Ospreys at the top of the table due to points difference,  and both teams are on a winning run, but Leinster have not lost to a Welsh region in Dublin since Ospreys took the title there in May 2010.

A third Irish Province, Connacht are also in action on Friday, welcoming Benetton Treviso to the Sportsground, each team will be looking for a victory to restart their season after suffering dips over the last couple of rounds.

Both Italian outfits are involved on Friday night as Aironi visit Edinburgh, and with both teams at the wrong end of the table victory would be a welcome boost for either, Aironi in particular are still looking for their first away win.

It's top versus third on Saturday when Munster travel to Swansea to play Ospreys. Munster were the last Pro12 team to win at the Liberty Stadium, so this is likely to be a hard fought clash.

The round wraps up on Sunday with Glasgow Warriors travelling to Wales to face Newport Gwent Dragons. Another Warriors victory would see them equal their record for their best ever winning run in the tournament.

We look at all of the Round 10 matches:
