Manchester City were searching for a third goal at Cardiff back in September and, as Leroy Sane advanced towards the area, there was no room for Raheem Sterling to make one of his blistering runs in behind. Sane offloaded the ball to Ilkay Gundogan and Sterling, occupying a harmless space between five home defenders with his back to goal, barely moved. When he did, it was to take two small steps forward into the "D" before he and City sprang to life. A quick gesture to Gundogan, a sharp ball into feet, a one-touch lay-off later and within seconds, the Germany international had found the far corner. The finish was superb but the goal owed everything else to Sterling's coolness amid a sea of bodies.
