Pep Guardiola warned many hurdles still lie in the way of Manchester City and a fourth Premier League title in five years after sweeping aside Brentford 2-0 to go 12 points clear at the top of the table. 

Guardiola’s men were not at their scintillating best at the Etihad, but still had far too much for a Brentford side that risk being dragged into a relegation battle. The Bees had held out bravely for 40 minutes until a mistimed tackle from Mads Roerslev brought down Raheem Sterling and Riyad Mahrez coolly slotted away the penalty.
