Referee Mark Clattenburg suspected the challenge was one deserving a red card but clearly had doubts as his body language revealed immediately.
Either he did not have a good enough view or perhaps doubted his perception — he could well have been affected as he had sent Kompany off on the last day of last month during Belgium’s win over Israel.
In such situations, you need a second opinion and Clattenburg understandably referred to his assistant Jake Collin who erred on the side of caution and so Kompany escaped.
A review of a replay of the incident would have confirmed Clattenburg’s initial suspicion and resulted in the correct decision but we have to wait a few more years before that will happen. – Daily Mail
