Algeria's Riyad Mahrez opened his Manchester City account after scoring twice to help his side to a 5-0 thrashing of Cardiff City in the Premier League on Saturday.

Sergio Aguero also marked his 300th appearance for City with a familiar landmark goal to set the resurgent champions on their way to a magnificent win.

Aguero helped City rebound in emphatic fashion after their worst performance of the season in the home Champions League defeat by Lyon as a typical sharp, close-range finish from Bernardo Silva's pass saw him notch his 205th goal for the club.

Aguero's close-range strike just after the half-hour opened the floodgates with Silva heading home three minutes later and Ilkay Gundogan firing home a glorious third before the break to guarantee Cardiff's winless league start continued.

City, then able to stroll as they extended their unbeaten league run to 12 matches, celebrated further when record signing Riyad Mahrez joined the party with two superb second-half goals, his first for the club.
