Manchester City fired an ominous warning to their Premier League title rivals Liverpool and Arsenal with a 5-1 hammering of Luton that sent them to the top of the table.
The goals were shared around, with one for Erling Haaland and another for Mateo Kovacic, whose hit from the edge of the box was the pick of the bunch.
Luton notched a consolation through Ross Barkley but were well beaten.
