It was more todo with Aluko getting cramp, Mackie on for him as opposed to Fyvie who was coming on for McDonald I think.
That isn't being two faced atall, it's more to do with "a time and place" you know, the abuse Mackie got was un called for, FFS he had just been stripped and away to go on, the other night most of the guys played for the whole game and put in a gutless performance.
