Gabriel has returned to first team training just 34 days after going down in a crumpled heap against Manchester City in pre-season.
The Brazilian centre-back suffered ankle ligament damage in a clash with Kelechi Iheanacho in the dying moments of the 3-2 win and was initially ruled out for up to two months.
Ahead of the Watford game, Arsene Wenger was optimistic that the 25-year-old might make a quicker return stating: “He’s progressing very well. He’s ahead of schedule. We said six to eight weeks and we think it could be six.”
It looks as though his recovery has been even swifter. It’s unlikely Gabriel will be part of Arsenal’s squad for the visit of Southampton on Saturday, but he should be available soon.
Laurent Koscielny, Rob Holding and new signing Shkodran Mustafi will hold the fort until then.
