ROB HARLEY says Glasgow are adopting a one-game-at-a-time approach to the five- game run-in of the PRO12 regulation season.

Warriors head for Munster tomorrow night on the back of a winning run of three home games that has propelled them into fourth place in the table and residency in the final play-off slot.

But Glasgow have not won in Limerick since May 2008, and Munster have just given a six-try thumping to Toulouse to book a Heineken Cup semi-final place, so Harley was not about to underestimate the size of the task ahead.

The Warriors blindside said: "There is no point looking any further forward than the Munster game. There may be only five fixtures of the regulation season left but you have to take it one game at a time.

"There is no point saying we will need this, or that from the run-in. All that matters is the next game and that has been our approach for this trip to Thomond Park and will remain the case in all of the games we have left.

"We know that every time we go to Munster it is going to be a battle and we will get nothing easy.

"With them having thrashed Toulouse last week we are well aware their tails will be up."

Harley added: "But we must focus on ourselves. Although we have put together a three-game winning run there are still aspects of our play we need to improve.

"Last week against Treviso our line-out was not what it should have been and that is one area we have worked very hard on ahead of the Munster game."

Warriors have been handed a pre-match boost: Munster skipper Peter O'Mahony is out with a shoulder injury.

But Harley says the Munster men have enough depth to cope.

The busy flanker said: "They have a conveyor belt in terms of the depth they have to absorb his absence and draw upon.

"Also given they have just had a huge European game against Toulouse you don't know how they will shuffle their cards.

"So there is no point worrying about Munster. It is about making sure we produce the best possible Glasgow performance."
