FGR fans on their forum seem to be happy with a draw, many expecting a defeat.
They are also having a call to arms for fans travelling to Sixfields. Whereas I don't expect too many to infiltrate the home sections, which could cause untold problems, don't be surprised to see travelling numbers in the high nineties!
Luckily they're easy to spot. They'll be the ones telling everyone about the benefits of veganism OR demolishing a dozen pies each
