Manchester City returned to winning ways in style with a thumping win over Southampton that moves them 14 points clear at the top of the Premier League table.
Riyad Mahrez and Kevin de Bruyne both scored twice as City delivered an emphatic and instant response to their defeat in Sunday's Manchester derby, which had ended a 21-game winning run.
This was not the disciplined display typical of many of City's victories this season but their incisive attacking, aided by some helter-skelter Saints defending, meant they still ended up convincing winners.
A strong Southampton start counted for nothing when Ryan Bertrand switched off and, from Oleksandr Zinchenko's cross, De Bruyne swept home from close range after Alex McCarthy had kept out Phil Foden's initial effort.
