Devastated defender Steven Taylor has admitted Newcastle had only themselves to blame for an unprecedented fourth successive derby defeat by Sunderland.
Sunday's high-octane clash at St James' Park looked to be heading for a first goalless draw since May 1990 when Adam Johnson settled it with a 90th-minute winner, his third goal in as many visits to Tyneside.
Victory was little more than the Black Cats deserved after creating the better chances throughout the game, but it arrived with the Magpies on top and pushing for a winner of their own.
Taylor said: "We can't believe it. We were looking at the clock and thinking it would be a draw. We were just looking to see the game out.
"Maybe we got a bit carried away. Sometimes you have to shut the back door. It came from our own set-piece so we only have ourselves to blame.
"I just can't believe it's another season that we have been beaten."
Newcastle went into the game desperate not to set a new record for consecutive Tyne-Wear derby defeats and knowing they had a debt to repay to their fans after losing the last two editions on their own pitch 3-0.
Taylor, who had two stitches put into a head wound after a nasty collision with the post as he denied Steven Fletcher a certain goal, was left to rue a lack of cutting edge at the other end of the pitch. He said: "We had the chances. Everything was at the keeper - straight at him. We are gutted with that, but Adam Johnson is a top-class player and he proved that today."
Jonas Gutierrez has thanked friends, family and football fans for their support after the Newcastle man made his comeback having successfully battled testicular cancer.
The Argentina international played as Newcastle beat West Ham 4-1 to advance into the quarter-finals of the Under-21 Premier League Cup. The former Real Mallorca man, 31, captained Peter Beardsley's side and played for 88 minutes.
Despite moving on loan to Norwich last year, Gutierrez has been assured of a role in Newcastle's first-team by manager Alan Pardew.
