Ilkay Gundogan scored twice as Manchester City moved to the top of the Premier League for the first time this season with an outstanding 5-0 victory at West Brom.
Pep Guardiola's side stretched their winning run to 11 straight matches in all competitions on Wednesday (AEDT), a sequence that has again seen City emerge at the forefront of the title picture after a rocky start to the campaign.
West Brom, then under Slaven Bilic, had been the last team to stop City winning when these teams met in mid-December, but Sam Allardyce's side were completely outclassed at The Hawthorns despite the absence of Kevin De Bruyne, the injured PFA Players' Player of the Year winner.
Joao Cancelo's first Premier League goal separated a first-half Gundogan double, which Riyad Mahrez and stand-in captain Raheem Sterling added to either side of the break.
West Brom's best spell came in the opening two minutes as City were penned in under an aerial barrage before countering through Phil Foden, whose low deflected shot was touched onto the post by Sam Johnstone.
Johnstone was helpless from City's next attempt, watching the ball nestle in the bottom-left corner after Gundogan controlled Cancelo's long pass and finished expertly.
The goalkeeper was then left awfully exposed for the second as West Brom defenders appeared to stop playing when Bernardo Silva was flagged offside.
Cancelo had time and space to pick out the top-left corner with a gorgeous finish and the offside decision was overturned following a VAR review, meaning the goal stood.
Gundogan pinched the ball from Romaine Sawyers and slid a left-footed effort beyond Johnstone before the half-hour mark, and it was 4-0 heading into half-time as Mahrez moved inside from the right and lashed past the keeper.
The same pattern of play continued following the restart and, although Rodri's blast clipped the crossbar, City only had to wait until the 57th minute for Sterling to turn in Mahrez's first-time cross, finally then easing up slightly to spare their struggling hosts further punishment.
