Steve Tandy says Ospreys’ Boxing Day victory over Scarlets will count for little if they can’t back it up with a win over Newport Gwent Dragons on Friday.

Ospreys have won their last four GUINNESS PRO12 fixtures since their 19-31 reversal in Glasgow on November 1 and they have not lost to a fellow Welsh region at Liberty Stadium since Dragons were the visitors in October 2010.

The omens all looks good for Tandy’s men with the Ospreys having won their last seven encounters with Dragons in the PRO12 since the Men from Gwent were victorious 21-20 at Rodney Parade in January 2012.

The Ospreys came through a narrow encounter 26-27 against Scarlets last time out and Tandy wants his team to keep their good run going as they look to add the Dragons name to the growing list of teams they have dispatched of.

Dan Biggar will be rested for Ospreys with Sam Davies taking his place while Jeff Hassler, Dan Baker, Nicky Smith and Aaron Jarvis all come in.

"It was an important win on Boxing Day but it won't count for much if we don't follow it up with a good performance against the Dragons,” said Tandy.

"There's plenty to work on this week and that's a good place for us to be in, with the win but knowing where we need to improve.

"We're expecting a difficult afternoon against the Dragons, as is always the case. They have been in good form, won three from four in December, are doing well in Europe and were really unlucky not to win on Sunday.

“They'll come here full of confidence, so we'll have to be at our best. There's no margin for error now and that adds spice to every game that we play.”

Newport Gwent Dragons’ three game winning run in all competitions ended with their single point defeat at home to Cardiff Blues on Sunday.

Dragons are one of only three teams to have not won on the road in the GUINNESS PRO12 this season with their most recent away win being on a trip to Treviso in March.

There are five changes for the Dragons with Sarel Pretorius and Boris Stankovich returning from injury in place of Charlie Davis and Phil Price while Lloyd Fairbrother, Ollie Griffiths and Ed Jackson all come in and skipper T Rhys Thomas is looking for a reaction from his side.

“If you go so high when you win and then so low when you lose then it will be a hard life as a rugby player and a long career,” said Thomas.

“We need to be a level par – don’t say too much when you lose and even less when you win.

“As individuals I suppose you have to use the frustration and I am sure the boys will be looking to put it right on Friday, but it’s no different to any other game for us, we always play with that edge because we know it will be a long afternoon if we don’t.

“I don’t think I’ve been here and in a warm-up where I’ve felt the boys aren’t on the money because we don’t have that luxury.”
