Kai Havertz struck at just the right time for Arsenal after the Gunners had incredibly gone 3-2 down in their match against Luton.
The Hatters had fully deserved their lead after standing toe-to-toe with Mikel Arteta’s table-toppers, but as so often happens when a team scores, they switch off.
Havertz, who has been in a rich vain of scoring form of late, was on hand again to bundle the ball home, puncturing the atmosphere that Ross Barkley’s third for the hosts had generated just a few minutes before.
