GLASGOW coach Sean Lineen admits he is facing a real selection dilemma ahead of Sunday's crunch European tie with Montpellier at Firhill.

Lineen made 10 changes for the 14-14 draw against Newport Gwent Dragons two days ago and handed stand-off Ruaridh Jackson his first start of the season following a hamstring injury.

There was also a shock recall for No.8 Johnnie Beattie following his loaning out to Ayr for British and Irish Cup action.

With Beattie impressing on his 100th appearance for Warriors, as part of an all-new breakaway unit with Chris Fusaro at openside and Calum Forrester returning from long-term injury at blindside, Lineen knows he has big decisions to make ahead of the Heineken Cup Pool Three fixture.

The Glasgow coach said: "We freshened things up for the trip to Dragons and the boys that came in have left me with some really tough calls to make later this week ahead of the visit of Montpellier.

"I thought our back row were superb and all three of them really fronted up.

"It was a big game in particular for Johnnie and he had some great carries and some big hits and I thought the hunger was back with him.

"Chris was outstanding at openside and underlined why he is pushing John Barclay all the way for that position, and considering that was Calum's first game since March, he was first class.

"Any coach will tell you that picking from a position of strength is what you want and when I look back at last season, the contrast is unbelievable."

There is no doubt Sunday's match represents the pivotal fixture in Warriors' Pool Three campaign.

With a quick-fire return to the Stade Yves-du-Manoir next up on Sunday week and the French side sitting bottom of the section, a Warriors win in five days' time would surely knock the stuffing out of the Top-14 outfit's Euro hopes.

Both of Warriors' new signings, David Lemi and Rory Lamont are available for the Heineken Cup campaign and it looks likely the duo will take the field on the wing and at full-back respectively against the French.

Irrespective of any selection dilemmas, the Warriors coach has no doubt about the importance of Sunday's game.

Lineen added: "The fact that it is the first of the double header with Montpellier would allow us to really damage them if we can get the win."

lFinlay Gillies, 22, has been rewarded with a professional contract until next summer following his fine form for Warriors this season.
