Geordan Murphy has warned his fellow first-team fringe players they must be ready to grab their chance if Ireland coach Eddie O'Sullivan comes calling.

O'Sullivan has opted to give the same side that struggled against Namibia a chance to redeem itself in Saturday's second clash with Georgia.

The only new face is Shane Horgan, who returns to the right wing following injury, but if O'Sullivan's loyalty is not repaid then he is unlikely to be so forgiving for a second time.

Murphy is one of the players Ireland could turn to if their World Cup campaign continues to falter and the gifted Leicester utility back knows patience is key.

"For the guys who aren't getting a run it's difficult because everyone wants to play. But what we can we do?" he said.

"We just have to remain positive. This is a team effort and we have to try to do our best as a team.

"You never know what's going to happen. It doesn't look likely that some of us are going to see a lot of game time. But anything can happen.

"We have to just keep training hard with a view to ensuring that the guys going out are well prepared.

"We have to work hard in training when we play against the guys that are starting, but we also have to make sure we're in shape if we do get a shot."

O'Sullivan has a clear picture of Ireland's strongest XV, which suggests a small group of players may have a frustrating few weeks ahead of them.

But Murphy understands the coach's reluctance to swing the axe for Georgia.

"I'm sure the guys are disappointed. Everyone wants to go out and play," he said.  "If the lads had done a more effective job against the Namibians, Eddie might have been able to give a few more of us a run.

"I suppose, from Eddie's point of view, we needed a little bit of continuity in the team and it was important for him to pick the same players."

Murphy will be more eager than most to force his way into the side after missing out on the last World Cup with a broken leg.

The 29-year-old was in sensational form and an unknown quantity in the southern hemisphere until his hopes of travelling to Australia were ended during a warm-up match against Scotland.

"It's a huge thing for me to be here and I'm enjoying it. We've only had one or two days off so it has been hard work," he said.

"But we've gone in town and had a look around and it's a nice city. The team hotel is a bit remote all right but we're here to do a job, not to enjoy ourselves."  PA
