McClaren claims he didn't hear the boos from the Newcastle fans at the final whistle ... saying the players were applauded.
Not only is he thick as shit ... but he is deaf too!
McClaren's side are two points from safety after successive defeats over Christmas but the boss felt they should have had a second-half penalty when Aleksandar Mitrovic missed his kick and felt he was pulled back in the area.
He said: "It is a game we never deserved to lose.
"It is a blatant penalty, I have seen it three or four times and the referee when he sees it again will realise he has made the wrong decision. The defender has grabbed Mitrovic around the waist and has put him off his shot before we lost to a soft goal at the end.
"We have ended the first half of the season with a bit of consistently but have been unlucky with our last two results.
"I am more disappointed for the players because they are fighting and showing attitude and endeavour.
"I am interested to know if there were boos (from fans at the end) because I think the team went over and were applauded.
"Sometimes you don't get what you deserve in football and the last two games we haven't but we have to continue what we have been doing knowing - and I know - it will turn around."
