Angry Steve McClaren has blasted referee Bobby Madley after a controversial penalty and red card changed the course of the derby.
Newcastle had dominated the first half against Sunderland at the Stadium of Light but then Steven Fletcher was bundled down by Fabricio Coloccini for a penalty in the 45th minute.
The Argentinian captain was given his marching orders.
McClaren was left fuming as he didn't believe it was a penalty or a red card. Adam Johnson netted before Billy Jones and Fletcher compounded the misery further.
McClaren said: "I don't think frustrated is the word, I am angry and disappointed.
"Two decisions have cost us the game in which we were totally dominant.
"It was a perfect performance first half, going into a derby and I have never felt so relaxed.
"The crowd got them irritated, we had no chances against us. We should have had a penalty on Gini Wijnaldum.
"Then straight away we get a penalty against, in my opinion that was wrong and unbelievable.
"I think 3-0 flatters them but we can't do anything about it.
"We are not making excuses but even in the second half, I fancied us.
"We were still trying to score and go forward, they had three shots and three goals.
"Even with 10 men if we had got one, they'd have got very nervous."
