Sharp red card halts any Blades comeback
Sheffield United had many chances of their own to score over the course of Saturday afternoon and they would have still sensed a chance to equalise in the final stages of the game.
However, they would have needed all 11 of their players – and particularly their strikers – on the field right up until the final whistle.
This was not the case as former Saints man Billy Sharp was shown a straight red card for a challenge that caught Stuart Armstrong high on the leg.
With that, any momentum that the Blades had hoped to build-up drained away and Saints had their win.
