Arsenal boss hits out at officials after Champions League defeat

Question

Can someone tell me why Arsenal boss hits out at officials after Champions League defeat?

Answer 1

He said The fifth officials are useless. We’ve had Emmanuel Eboue kicked-off the park and a definite penalty turned down — that’s more than bad luck. What are the fifth officials doing?
