6 referee calls that made the world question football officiating

#1 Gibbs' sending off (2014)

Oxlade-Chamberlain survived, Gibbs was sent off

In March 2014, Arsenal suffered a humiliating 6-0 defeat to Chelsea in the Premier League. Referee Andre Marriner made an error in the 17th minute of the match when he wrongfully sent off Kieran Gibbs for handling the ball.

It was teammate Alex Oxlade-Chamberlain who had, in fact, dived to tip away Eden Hazard's shot with his hand. Despite Chamberlain admitting that it was him who had committed the offence, Marriner stood firm.

Maybe it was the colour resemblance between Chamberlain and Gibbs on top of the split-second decision that caused the confusion. Marriner later apologised for the mistake.
