City were suddenly dominant, De Bruyne at the heart of everything, and his nodded header into the middle brought a mis-kick from Ilkay Gundogan, but that took the ball into the path of Omar Marmoush to lash home an equaliser. Within two minutes of the restart, City were in front. De Bruyne’s lay-off found Mateo Kovacic, and he ran onto it to finish calmly on the stretch. Three became four when Ederson pinged a glorious ball over the top of the Palace defence, James McAtee beat the offside trap and went round Dean Henderson, and there was still time for Nico O’Reilly to join the fun, his volleyed strike flicking off Nathan Clyne on the way to the bottom corner.
