Phil Foden and Bernardo Silva struck as Manchester City maintained their pursuit of Premier League leaders Arsenal with a hard-fought 2-0 win over Newcastle.Foden opened the scoring at the Etihad Stadium after a superb run before Silva came off the bench to secure the points from a feisty encounter in the second half.Foden's brilliant 15th-minute effort, albeit coming with the aid of a deflection, gave the champions a deserved interval lead but Newcastle, looking to get back to winning ways after a poor run, fought back.The Magpies were the dominant side in the early period of the second half and it took the arrival of Silva, who scored within moments of coming on, to settle City's nerves in the 67th minute.His strike took the sting out of Newcastle's game and what has been a fine campaign continues to look like it is running out of steam.As well as losing last week's Carabao Cup final, Eddie Howe's side have now gone five Premier League games without a win.Yet as Newcastle tire, Foden appears to be getting going.The England midfielder has endured a frustrating few months since the World Cup due to injury and illness but he has now scored four goals in the past three outings.He stamped his authority on this game after City had already gone close with Ilkay Gundogan heading over from a Jack Grealish cross.Newcastle had also begun positively with Anthony Gordon, making his first start for the club, getting an early look at goal but Kyle Walker prevented him getting a shot away.Foden made his mark when he took a Rodri pass in his stride and cut inside from the right before jinking his way through the area.
