The January signings from Legia Warsaw and Villarreal were both in training this afternoon.
This week they signed Gabriel Paulista from Villarreal. The Brazilian talent arrives to add some strength in depth to the defensive department. After selling Thomas Vermaelen this summer they failed to replace him and they have needed to use the likes of Mathieu Debuchy and Nacho Monreal at the heart of defence.
Meanwhile the club have long needed a new defensive midfielder. They snapped up teenager Krystian Bielik from Legia Warsaw earlier in the month, although he is considered as one for the future.
But the pair of Arsenal newbies have been snapped in training ahead of the Arsenal game with Aston Villa this weekend.
The consensus has been that Bielik will not be featuring for the Arsenal first-team for a while. However, it seems that Arsene Wenger is happy to have him training with the first-team.
He also got a treat, as he was training alongside Arsenal legend Robert Pires, who is currently keeping fit by training with his former team.
Gabriel on the other hand is fully available for the weekend and looked fresh and involved in the training session this afternoon as he hopes for a Premier League debut come Sunday.
Here are some of the best snaps of the two men in Arsenal training this afternoon...
