Arsenal will have to sit back and watch their rivals play before them this weekend, meaning the focus in training is all the more important.
The squad welcomed back a trio of talent this week, with Hector Bellerin, Francis Coquelin and Kieran Gibbs all returning to action following minor injuries.
Arsene Wenger revealed Theo Walcott is still a week away from contention and Mertesacker will have to wait until February to be considered in the selection.
As well as that, Carl Jenkinson is expected to finalise a permanent move away from the club in the coming days, so this might be the last time we see him in Arsenal merch.
Here’s some of the best pictures from London Colney today:
