According to the latest news, I saw that he did not have a serious injury. That's good news for him, Arsenal would probably struggle without him.
Their next game is against Everton and they need to defend well. If one of the players is missing from the team, their chances of conceding a goal are much higher. Even though Everton started this year badly, the team needs to get a comfortable win and be highly motivated for the next games
Nah I don't think we will struggle without Gabriel. We have signed lot of centre backs to still find it smooth if situation like this happened. I think we still have some good centre backs to replace Gabriel. If you look at the first 3 games, we played with White and Saliba as centre backs and we still did decent. However I do admit that White is much better option as a right back but there is also Kiwior who can be centre back for us in next game.
I still expect Arsenal to win the game against Everton smoothly.
