It was not a good game for Mr Scott. I understand he was a late replacement for Andre Marriner and therefore may not have had the opportunity to get himself fully into matchday mode.
Penalty - poor decision but the defender gave the attacker the opportunity to go to ground
Dismissal - this was a reckless tackles, no more, no less. Yes really, believe me it was only reckless. The contact was made after playing the ball.
Offside decisions - he relied on his assistants to indicate the offences
As a team I don't think they were completely attuned to each other's game and those little things led to a number of errors.
