I only saw this first half of this but didn't see what all the Sunderland fans social media fuss was about. Roberts went down far too easily in the box, could have easily been booked for simulation. Good spot from Whitestone not to give it.
Then for the Diallo card referenced above, Whitestone allows him to continue his run towards the area until he's upended by Eccles. That trip gets a reaction from Diallo and several Sunderland players - mainly defenders charging 25+ yards to get involved rather unnecessarily. Eccles rightly booked for the foul, Diallo booked for his reaction. Overall, seemed a very tetchy first 45 minutes, mainly due to poor player behaviour rather than the referee's performance.
Would imagine there'll be an FA charge on it's way to Sunderland for failing to control their players.
