Arsenal secured progression into the knockout stages of the Champions League after a 6-0 thumping of RC Lens.
Arsenal's 6-0 win over RC Lens was as convincing as one could have hoped form prior to the game, and in a 14-minute spell, the Gunners slammed on four goals as Kai Havertz scored his second goal in as many games.
It was one way traffic for most of the first half as Lens struggled to get anything going as Arsenal looked to be back to its devastating best.
With Arsenal really failing to hit the strides of last season, the win over Lens looked like the "old Arsenal" as devastating football returned to the Emirates.
The Gunners will now have to put their Champions League exploits to one side for the next three weeks as the Premier League takes center stage before a trip away to PSV to finish the group stage.
Arsenal now will get to focus on the Premier League as Wolves, Luton Town and Aston Villa are next up on the schedule as it looks to maintain its lead in the league standings.
It will be anything but easy, however if the performance against Lens is anything to go by, then it will take something to stop this Arsenal team if it gets into the groove.
