Anyone know why Maastricht are 13/5? They have drifted from 9/4 earlier today. They seem to be in good form having won four and drawn one of their last five and won their last three away from home. Den Bosch are pretty poor, having won only one of their last four at home and having only won two games all season. May be way off with this one but it looks like a good bet at the price on offer?
