Sergio Aguero scored twice as Manchester City put up a ruthless display; beating Crystal Palace 4-0 at the Etihad on Saturday.
The Argentine scored on either side of half time and set up a third late on, as the Citizens returned to winning ways by cruising past their sorry opponents.
The win takes City above both Arsenal and Leicester City to the summit, ahead of the Foxes’ clash against Aston Villa in Saturday’s late kickoff.
The hosts found the all-important opener through Fabian Delph’s long-range attempt after earlier fruitless tries.
That breakthrough provided City with the spark they needed to push on and, after having a slim penalty shout turned down, Aguero bagged his first ever Premier League goal against Palace with a similar attempt from long range.
Hennessey was this time left wrong-footed by a big deflection off Scott Dann, putting the two-time Prem champs in strong control at the interval, with their league-high 11th goal from outside of the box this term.
After a tedious spell in proceedings, the Citizens finally made certain of the points thanks to Aguero’s second of the afternoon at the end of a fluid passing move.
Palace’s heaviest defeat of the campaign leaves them in eighth place, while for City this may well be the victory that truly kick-starts their season ahead of a gruelling few weeks.
