Rangers and St Mirren toiled their way through a goalless first half with scoring opportunities rather thin on the ground for both sides.
With the Buddies five man midfield, the home side are being swamped, meaning the forward partnership of Kris Boyd and Steven Naismith are having to drop deep in an attempt to get a feel of the ball.
St Mirren manager Gus McPherson will be hoping for more of the same in the second half before throwing on a couple of strikers in the last ten minutes to go for broke.
Kyle Lafferty is not a winger and that much is evident tonight so Ally McCoist and Walter Smith must contemplate throwing DaMarcus Beasley into the mix.
Rangers are going to have to get down the flanks if they are to break down the stubborn Paisley defence but Madjid Bougherra has been the standout player of the half and is a massive 20/1 with extrabet to get on the score sheet, incredible considering most other firms trade at around the 6/1 mark.
Rangers are now 4/9 (Bet365) whilst St Mirren are 14/1 (Bet365) with extra time priced at 6/1 (Skybet). Plenty of value on offer tonight it seems.
