Newcastle manager Rafael Benitez said his side must cut out the mistakes they are making "week in, week out" after a late own goal against Leicester extended their poor run of form.
Striker Ayoze Perez poked the ball into his own net in the 86th minute as he tried to prevent Shinji Okazaki scoring, giving Leicester a thrilling 3-2 victory at St James' Park.
Newcastle have taken just one point from their past seven matches, and the cushion between them and the relegation zone is just two points.
"These kind of mistakes, you cannot make in the Premier League," Benitez said.
"We have to learn and have more experience and manage it better.
"We have seen two or three situations with the same kind of goals. It is sometimes a lack of experience."
Lack of experience? Perez has been part of the first team for three seasons ... how long does it take?
