The Black Cats were already 1-0 ahead when Connor Wickham pounced on Cala’s poor back-pass at the end of the first half.
The Spaniard clearly pulled back the striker and, while he stayed on his feet, the official deemed that a genuine goal-scoring opportunity had been prevented.
Poyet claimed that the decision should be set as precedence for future refereeing decisions - pointing to the Matt Jarvis incident at the Emirates Stadium earlier this month as another clear example which merited a penalty.

“I think everyone saw the action of Jarvis. My idea was to ask in the referee meeting next year how we can convince the players to stay on their feet if they don’t get a penalty.
“If they give it, it means we can go out there and say stay on your feet and the referee will back you up, and that’s fantastic for football.
“Until today I’d never seen it. That meant you maybe needed to go into the dressing room and tell a player ‘why didn’t you go down?’ - which is not right.
“Now Phil has proved to all of football that it’s possible and that is fantastic.”
Cardiff manager Ole Gunnar Solskjaer refused to comment on the penalty incident but insisted that his side had not given up hope of surviving the drop just yet.
“The players have taken a big blow. We’ve got two games and we’ve got to win those two,” the Norwegian admitted.
“Two wins, that’s what we needed before today and we still have to go to Newcastle next week and try to win that one.
“I spoke to Wes Brown and we both think we can still do it. I think the two clubs know that both are still capable of it.”
