Gabriel has returned to training after missing out on the US tour with tonsillitis because he’s six.
The Brazilian was sidelined at the worst possible time with Per Mertesacker also being ruled out and Laurent Koscielny still on hospital. Pre-season was a great opportunity for him to show the boss what he has to work with for next season, although you’d expect Wenger would already know that by know.
A few youngsters also trained with the first team as they get ready for their penultimate friendly on Friday night.
Ainsley Maitland-Niles was included along with Chris Willock, Gedion Zelalem, and Krystian Bielik, all of whom could feature against Viking in the Viking Stadium in Stavanger.
Of those players, we could see Bielik remain with the first team ahead of the new season, but loans for all of them would seem to make the most sense.
