Having played all 90 minutes in Belgium's defeat to Italy on Thursday, Trossard started once again as they looked to bounce back against Israel. However, 37 minutes in, Trossard was substituted off, looking far from happy. The forward had been moving around gingerly in the preceding minutes with something clearly wrong, and Belgium coach Dominic Tedesco saw enough to take him off before further damage was done.
Arsenal went into the international break with concerns over the fitness of England duo Bukayo Saka and Declan Rice, while Riccardo Calafiori, Ben White and Takehiro Tomiyasu are also all out with long term injuries. With Trossard now also added to that list, Arsenal are now potentially missing six first-team players, the last thing Arteta needs before a tricky game against Nottingham Forest at the weekend.
