GLASGOW WARRIORS coach Sean Lineen has urged his squad to make history when Saracens visit Firhill tonight for their Heineken Cup Pool 4 showdown.

The Warriors need to beat the English giants by more than seven points, scoring four tries in the process and, at the same time, prevent their rivals from scoring four ties in the live Sky Sports clash (8pm).

But if they can pull off that feat then they will secure a place in the quarter-finals of European club rugby's premier tournament.

Lineen admitted it will not be easy to reach that part no other Glasgow team has reached before.

The Warriors coach said: "To be going into this home match with a quarter-final place at stake is a real achievement and it underlines the improvement and progress we have made.

"We are hoping for a gate of around 4,000 and, hopefully, the Glasgow and West of Scotland rugby public will come out in numbers.

"We need a big crowd because they can be the 16th man and the players will respond to that."

Lineen has made five changes, one of which is positional, to his starting line-up.

Speaking at the team run, which was held at Murray Park, Lineen said: "The boys are all fully behind what we are trying to do tonight. We know what we've got to do. The players know how important it is to win the game first and foremost and that's going to be hard enough."

On Murray Park itself, Lineen added: "It was fantastic training there, the players got a real buzz out of it. It's always nice to have a roof over your head when the weather's like this. The boys are looking very sharp and they are very focused."

Hefin O'Hare is re-instated in the backs with Thom Evans moving to the right wing.

In the forwards, Lineen has selected an entirely new front row with Justin Va'a and Moray Low graduating from last week's bench to link up with Fergus Thomson, who was rested for the trip to Viadana.

The former Scotland international says his Warriors must take Saracens on up front if they are to avenge a nailbiting 33-31 loss at Vicarage Road in the first meeting.

Lineen said: "That battle will be crucial as they are a very big team and they take a lot of pride in their scrummage. We need our pack to respond to the challenge of taking them on in that area.

"I am pleased that we have a strong referee in Alan Lewis and that may be very important."

Lineen added: "I would say that our scrum-half Sam Pinder and stand-off Dan Parks must really control the game and we need to know when to have the ball in hand and when to kick it in behind them."
