Rangers host Celtic in the old firm derby today, kick off 1230, and if previous such occasions are anything to go on, this will be a no-holds barred, no quarter given encounter. On the last 4 occasions Rangers have hosted the game, there have been 7 yellow cards and one red in the first half alone.
That's enough of an incentive for me to part with a tenner and accept Willy Hill's very generous EVENS (ought to be 1/10) that at least one card is shown in the first half.
