Ospreys Coach Sean Holley knows his side must rise to the challenge of facing English opposition they Worcester Warriors in the EDF Energy Cup this weekend
He said: "After a demanding fortnight in the Heineken Cup, we have to switch our focus to the EDF Energy Cup this weekend, and the unique and very different challenges which this competition presents. Worcester are a top side with some big names in the likes of Chris Latham, Pat Sanderson and Sam Tuitupou. They go into Sunday's game in a rich vein of form having scored over 100 points in their last two games, and they also achieved an excellent bonus point win in their first pool match in this competition, against London Irish, so we are under no illusions as to how Mike Ruddock and his team will be preparing for this game.
"We are delighted to welcome back Nikki Walker, James Hook, Lyndon Bateman and Jamie Nutbrown after injury, it's always good to see players returning to action and increasing the options available in the squad for a match-day. Jamie in particular is desperate to pull the shirt on again having only figured in two games for us to date, and we are excited by that prospect.
"We've selected a very experienced side, with 16 of the 22 having more than 50 Ospreys appearances to their name. We will need all of that experience for this challenge, but we are all looking forward to it immensely and hope that we'll have a big crowd behind as we look to build on last week.
"Our results have been good of late, but we feel that we can still improve in lots of aspects of our game. The players have been extremely diligent and focused this week and want to take a step closer to retaining this trophy.
"As we prepare for this game, we must congratulate our players selected for the Autumn International series this week. It is a credit to our organisation, and in particular to our players, that we can celebrate 50 per cent of the extended Wales squad coming from our regional family."
