Pep Guardiola says Riyad Mahrez is not yet functioning at the high level he reached last season.
The Manchester City ace is on the brink of matching Sergio Aguero's club record of scoring in eight consecutive games, as the Blues prepare to face struggling Norwich at Carrow Road tomorrow.
Mahrez scored from the penalty spot in the 2-0 win over Brentford after also netting from the spot against Fulham last weekend, and is out on his own as the club's top scorer this season with 16 - the only player in double figures.
