Poyet was convinced Baggies defender Joleon Lescott should have been sent off after being penalised for a fifth-minute foul on Danny Graham, and then saw a tight offside decision go against his team when Adam Johnson thought he had broken the deadlock in what proved to be a scrappy 0-0 draw.
He said: "It's onside. It's unfortunate from the linesman. You know what? I understand why he gave offside. Of course, in this situation when we needed it to go for us he made a mistake, but I am a little bit more disappointed with the other one, the red card.
"I think it was an easy decision. The ref was not giving the foul, the foul was given by the linesman, so I think the call for the red card should be the linesman and not the referee.
"What can I say without getting fined? It was unfortunate, the referee today."
