Arsenal are boosted by the news that two key first team players will be available for their coming games.
The Gunners have been without midfielder Thomas Partey for several weeks.
They have also felt the absence of summer signing Gabriel Magalhaes in defence.
According to a statement on the club website, Gabriel is now back in full training.
He should be available for the team's clash against Crystal Palace on Thursday.
The club have also confirmed that Thomas Partey is back in training after recovering from an ankle problem.
He is unlikely to feature against Palace, but may make the bench.
