Phil Foden struck twice and set up another goal as Manchester City impressed in a 4-1 victory at Brighton & Hove Albion.
Ilkay Gundogan opened the scoring after being teed up by Bernardo Silva 13 minutes in.
Foden took the match away from Brighton with two goals in three minutes, the first of which came from a Jack Grealish pass.
His second was more fortuitous, Gabriel Jesus's shot glancing off him on its way into the net.
Brighton put the champions on the back foot for most of the second half and were rewarded when Ederson fouled Enock Mwepu in the area.
Fellow substitute Alexis Mac Allister scored from the spot with nine minutes remaining.
But Brighton's efforts fizzled out and Riyad Mahrez scored from Foden's pass in the final minute of stoppage time to add gloss to the scoreline.
City leapfrog Liverpool into second on 20 points, two behind Chelsea. Brighton stay fourth, five points further back.
