Some horror tackles on the player on his debut in Brazil's match against Bolivia means he might have to rest. Although I still haven't found any news about Gabriel's current condition but the possibility of him resting for a few weeks is still possible and this could be a problem for Arsenal who are ready with some matches and a busy schedule.
Arsenal's coach Arteta was already starting games without him this season, so he will be able to adjust for the time being hopefully the injury is not going to be a long one. Kiwior will most likely be the one to start against Everton. Everton have had a bad start to the season, they may want to change it when they play against Arsenal.
Arteta's biggest hopes is that he will not have more players injured in this international duty.
Right, in the few matches Arsenal have played so far also in reality, Gabriel is not always the first choice in the starting eleven. Therefore, if Gabriel gets injured in this international match, then of course Arteta can still play other players to be included in the starting eleven. After all, I'm sure Arteta has learned from last season, so this season Arteta certainly has better preparation. Maybe one of them is, making second tier players have good quality too and that way, then at least Arsenal good performance will still be maintained. But indeed, however Arsenal have a difficult schedule after playing against Everton. Because Arsenal will play against PSV in the Champions League and after that, Arsenal will play against Tottenham in the Premier League and obviously Tottenham at this moment are also in good form.
