The last round of Pro12 matches before the start of the Six Nations opens on Friday at Rodney Parade, where second placed Ospreys will be looking to consolidate their play-off place with a victory over Newport Gwent Dragons.
Ospreys however have only won once at the venue since the Regions were formed in 2003.
Also on Friday Edinburgh welcome Ulster to Murrayfield, a ground where the hosts are building a good home record; Ulster on the other hand are finding it difficult to gather points on the road this season.
The remaining fixtures all take place on Saturday, starting with Aironi's game against Connacht in Viadana. If the Italian outfit are to improve on last season's final standing, a repeat of their previous victory in this fixture could see them move off the bottom of the table, other results permitting.
There are two games in Wales on Saturday, Cardiff Blues hosting table-topping Leinster whilst Glasgow Warriors visit Scarlets. Warriors, along with Munster, were the only two teams who changed places in the table after the last round, the Glasgow outfit's victory over Edinburgh lifting them above the Munstermen in the play-off zone.
Fifth-placed Cardiff Blues still have a game in hand over their nearest rivals, but any slip up to the leaders could see the gap between themselves and the play-off zone widen, something Blues will hope to avoid going into the break.
Finally Munster, looking to bounce back from defeat in Ulster, welcome Benetton Treviso to Thomond Park. The Italian side may have won three of their last four matches away from home, but face formidable opposition both on and off the pitch in Limerick.
We look at all the Round 13 action!
Friday, January 6

Newport Gwent Dragons v Ospreys

The Dragons most recent success in the Pro12 came at home to Ulster on 30 September. The Men from Gwent have lost all three fixtures against fellow Welsh Regions this season.

Ospreys only away win in their last six trips was 17-6 against Connacht in Galway in the Pro12 on 26 November. The Swansea based outfit have not beaten a Welsh rival on their own soil since they visited Scarlets on 2 October 2010.
Ospreys solo win in their last four encounters with Dragons was 42-10 at Liberty Stadium on 7 May 2010, whilst Ospreys have won just once at Rodney Parade in nine visits since the region was formed: 27-13 on 8 May 2007.

Aironi v Connacht
(Stadio Zaffanella - 16.35)
Aironi beat Italian adversaries Benetton Treviso 27-13 on 23 December last time out at Stadio Zaffanella and are attempting to win back to back home games for the first time. Aironi's only previous success against an Irish side came in this equivalent fixture in Viadana last season.
Connacht seem unable to break out of their losing streak which now stands at a dozen matches in all competitions since they beat Newport Gwent Dragons 17-13 at the Sportsground on 23 September. Connacht's only away win in the Pro12 since September 2010 remains their 11-9 score at Treviso in round one this season.
Each side won its respective home encounter when the two teams met last season.
Referee: Andrew McMenemy, (Scotland)
Assistant referees: Alan Falzone, Stefano Roscini (both Italy)

Cardiff Blues v Leinster
(Cardiff City Stadium - 18.15)
Cardiff Blues' last seven matches have all been won by the home side on the day. The Blues have been victorious in their last four home games at the City Stadium, but strangely have won just one of their last four matches against the Irish provinces at the venue.
Leinster have won their last seven encounters in all competitions, since their 16-16 draw in Montpellier in the European Cup on 12 November. The Leinstermen, who sit proudly atop the Pro12 table, have won their last nine games in the tournament.
The Blues' only win over Leinster in their last nine meetings since May 2007 was 11-3 in this equivalent fixture at the City Stadium last season.
Cardiff Blues: TBC

Scarlets v Glasgow Warriors
(Parc y Scarlets - 18.15)
Scarlets have recorded only one loss in their last seven Pro12 contests: 17-24 at Ulster on 2 December. The Welshmen's solitary home defeat this season in this tournament was 10-15 to Leinster on 24 September. Scarlets have won their last five matches against Scottish opponents.
Glasgow Warriors climbed to 3rd spot in the Pro12 log following their 17-12 defeat of local adversaries Edinburgh at Firhill on New Year's Day – their highest position in the table since round 18 in 2009/10. Incredibly the Warriors have drawn their last three away games in all competitions. Glasgow are unbeaten in their last four games against Welsh regions.
Scarlets did the double over Glasgow last season, whilst the Warriors have won in two of their three previous visits to Parc y Scarlets.
Glasgow Warriors: TBC

Munster v Benetton Treviso
(Thomond Park - 20.15)

Benetton Treviso have won two of their last three encounters in the Pro12, and have won three of their last four matches away from home in the tournament.
Munster suffered a first ever loss to an Italian side when they last met Treviso at Stadio Monigo in February.
