Ospreys Coach Sean Holley commented: "We go into the final Christmas derby on the back of an excellent result at the Liberty Stadium on Saturday, and we face a Blues side that has been playing really well this season. They have a settled side and that has resulted in them enjoying a very productive time of late, with some good performances and notable victories. We enjoy a healthy rivalry and we are well aware that the Arms Park is a difficult place to go and get a result. But, we have gone there and won in the past and, with a full house expected, we are excited about the prospect of another big occasion.
"The next two matches, against the Blues and Munster, are very important games for us, in terms of keeping our momentum going in the Magners League. Our focus is entirely on maintaining a strong challenge at the top of the table before attentions turn to European competition again as we want to ensure that we have it all to play for, in terms of the Magners League, by the time the next crucial phase of the season comes around.
"We have had to manage our squad closely over this busy period and the performance against the Scarlets last time out showed the great character within the squad and the belief in our ability that we have. There were some great individual performances, but most satisfying was the all round team showing in the second half to overpower a very determined opposition. We've only had a few days to prepare for this match, but after a quick turnaround, the 22 selected are entirely focused on the challenge that lies in store and are looking forward to enjoying another derby match in front of a big crowd, with a passionate atmosphere."
