Arsenal manager Mikel Arteta faces defensive uncertainty as key players Gabriel, Riccardo Calafiori, and Jurrien Timber suffered injury scares during the international break, adding to existing squad concerns ahead of crucial matches.
The Premier League leaders went into the fortnight boasting one of the meanest defences in Europe but have seen three of their key men involved in injury scares.
Injuries to Gabriel and Riccardo Calafiori had already caused alarm before full-back Jurrien Timber joined the list during the Netherlands’ 4-0 thrashing of Lithuania on Monday.
The Gunners, who host north London rivals Tottenham on Sunday and then Bayern Munich the following Wednesday, had registered a club-record eight consecutive clean sheets across all competitions before their 2-2 draw against Sunderland in their last match before the international break.
