8' - GOAL! Man City 1-0 Newcastle: Raheem Sterling with a typical Raheem Sterling goal.
Guardiola's side started this season as favourites to retain the title.
Newcastle United were beaten 2-1 by Manchester City at the Etihad Stadium on Saturday, however, fans were pleased with the performance of one man following the final whistle on social media.
The 22-year-old has struggled for game time in City's first three games of the season and was disappointing when introduced from the bench during the 1-1 draw at Wolves last Saturday.
The issue of Leroy Sane's attitude will not go away either.
At first, it appeared as if he would not be missed.
Sane spent the whole of pre-season with Man City, having been left out of Germany's World Cup squad.
City could have extended that lead.
Riyad Mahrez was unable to punish Salomon Rondon's slackness but, when returning Magpies captain Jamaal Lascelles passed straight to Benjamin Mendy, the full-back found Sterling to cut inside for an emphatic finish.
Bernardo Silva sent a delightful pass to Sergio Aguero and his cross saw Martin Dubravka make a remarkable point-blank saves from Fernandinho before twice denying David Silva on the rebound.
Newcastle hung in there, however, and equalised on the half-hour mark with a well-worked goal.
It was Yedlin's first Premier League goal and first goal anywhere since September 10, 2016, against Derby in the English League Cup.
City were shaken by that equaliser, and were still labouring to find a way back in front when they came up with a goal from nowhere seven minutes into the second half.
By now, the visitors were showing signs of tiredness.
