Ospreys 75-7 demolition of Treviso last time out was their biggest victory since the region was formed in 2003.

Ospreys’ only two defeats at the Liberty Stadium in the RaboDirect PRO12 since September 2012 were to Ulster and Glasgow in rounds 5 and 9 this season.

The Welshmen have won only one of their last nine contests with Irish provinces: 43-26 against Connacht in Galway in the PRO12 last September.

Munster continue to set the pace at the top of the RaboDirect PRO12 standings, having suffered just one defeat in the tournaments since round 3: 19-29 at Ulster on 3rd January.

The Munstermen have won all their six fixtures against Welsh opponents this season.

Munster have lost on their last three visits to Liberty Stadium since their 22-20 victory in April 2011.
