To make some sort of sense of it and I don't agree with Black's thinking by the way, was that firstly, the subsitution disrupts play. Secondly, I can only assume that his thinking was that Sinclair would run the channels/corners and act as an out ball. We were inviting pressure, depending ever so deep and simply giving the ball back to them too easily. However, from a coaches point of view, I would have brought on Richards and kept the five across the back. Black said that they had practised this for a few days, so why then make the back line a four after the sending off? Richards may have at least got in the way of some of those crosses! Still scratching my head too to be honest.
