The Spanish giants are back in England this week to take on the Gunners, a litle over a month since losing at Liverpool in their first League Phase game.
Atleti have since recovered in style by beating Eintract Frankfurt 5-1, and will be keen to maintain that momentum into their toughest test of the autumn and winter.
And [Diego Simeone](/topic/diego-simeone) has been buoyed by the inclusion of Nico Gonzalez in their travelling squad, having shaken off an injury scare suffered over the weekend.
Left wing-back Gonzalez was forced off with a head injury during the first half of Saturday's 1-0 win over Osasuna to throw his involvement at the Emirates Stadium on Tuesday into doubt.
But the 27-year-old has been named as part of the travelling party departing Spain for London today.
It remains to be seen if the defender will take to the field - with Simone set to issue an update at his pre-match press conference on Monday evening.
