TOMMY SEYMOUR has compared Glasgow's annual derby battle with Edinburgh to an FA Cup tie.

The two sides will battle it out over two legs for the right to claim the oldest trophy in club rugby, the fabled 1872 Cup, with the first encounter coming at Scotstoun in front of a sell-out crowd in tomorrow's 2.40pm kick-off.

The men from the East trail Glasgow by 15 points in the Guinness Pro12 table and have not won in the West of Scotland since they claimed a 25-16 success at Hughenden on December 27, 2003.

But while although Gregor Townsend's men will be looking to retain the famous old claret jug for the sixth year in succession, Seymour is wary of the underdogs' bite.

The Glasgow wing-king said: "You could compare it to an FA Cup tie type of thing when two Premiership sides come up against each other in a cup and past fixtures don't really determine how that is.

"They played a really great game of rugby against us last year and I felt we played well too. I don't know what you can put that closeness down to although derby matches have a way of bringing the best out of teams.

"They are also intense battles and kind of work as a separate sort of occasion as matches in the league and other sports to.

"So I think it will be an all or nothing type game in front of a sell-out crowd, it is definitely going to have a cup tie feel about it. No doubt about it."

Despite the stats weighing heavily in favour of another Warriors' triumph, Seymour is worried about an Edinburgh side he believes will play with the freedom of a team with nothing to lose.

The 26 year-old said: "If anything they go into this game as hot favourites to cause an upset. By the same token we will be doing everything in our power to maintain that dominance we have had over the past number of years. It is a toe to toe, equal match and it is going to be a great game of rugby.

"In terms of who the pressure is on, well you could argue both ways. You could argue it is nice we have the advantage of playing at home and that we have the record with us.

"But if there is a slight underdog's title, which I don't like, the underdogs tend to be the most powerful. They have nothing in their mind to lose. They want to make the breakthrough and nothing else matters.

"Yes it has been a while since they won it but every record comes to an end eventually and they will be determined to make that happen this year."

"So we have to be very wary of them and forget about bias, expectation and league positions. That doesn't come into the equation. I am not in the Edinburgh camp but I am sure that is the way they will look at it.

"They will be gunning for us. With the victory they had last week (48-0 v Treviso) their confidence will be right up there. They had a great session in Europe after the autumn internationals and kept it going against Treviso. Their confidence is flying high at the moment.

"So if anything Edinburgh will fancy their chances more than any other time before."
