Ayoze Perez scored a glancing header as Newcastle recovered from back-to-back defeats with victory at Leicester.
The Magpies are now 10 points above the relegation zone, with Perez easing the pressure on Rafa Benitez’s side by scoring his first away league goal of the season.
Leicester started confidently, having won their previous four matches under Brendan Rodgers, but they struggled to play through their disciplined visitors.
Salomon Rondon almost handed the visitors a spectacular lead when he struck the crossbar with a powerful free-kick from 35 yards.
Newcastle remained resolute and were rewarded when Perez struck the decisive blow with over half-an-hour played.
The Spaniard rose well inside the Foxes’ box to meet Matt Ritchie’s cross and nod the ball over Kasper Schmeichel.
Victory for the visitors lifts them to 13th place, while Rodgers’ first home defeat means Leicester remain in seventh.
Newcastle produce the model away performance
Leicester dominated the ball with more than 70% possession but Newcastle sat deep and restricted them to just five shots on target in the entire match.
Martin Dubravka saved well after a solo run by Harvey Barnes and a right-footed strike by Ben Chilwell as Leicester tried to force the initiative early on, but it was the visitors who posed the greater threat on the counter attack – and Rondon’s 15th-minute free-kick almost brought spectacular reward.
Benitez’ side were rigid in their shape and targeted Leicester midfielder Wilfred Ndidi, who lost the ball nine times in the first half, before springing clear in attack.
Ritchie whipped in two testing crosses with his excellent left foot before Newcastle took the lead, as Leicester failed to heed the warning.
Newcastle pinched the ball deep in the Leicester half once more before Ritchie delivered an accurate cross for Perez to convert for his seventh Premier League goal of the season and just Newcastle’s third win on the road.
