There was a bad news regarding Arsenal defender Gabriel Magalhaes this because seems he got injured after defend Brazil national team and while Brazil fight against Bolivia he was played as a starter and in the second half Brazil manager Fernando Diniz have to replace him because apparently Gabriel got injured and until now there was no certain news regarding his condition but Arsenal should be worried about this situation because we all know Gabriel is Arsenal key player and Arteta always be playing him for each matches and if Gabriel had serious injured i think it will be big lost for Arsenal because previously they have to lost Jurrien Timber who confirmed got long term injured and Arsenal will be lack of defender players
It's not a serious problem for arsenal. I have seen some perfect candidates that can fill his position. It's tomiyasu or saliba. These guys were also able playing as centre back to replace him.
Arsenal shall not feel frustrated after seeing he got injured. Injury was something that could not be avoided. It's a common thing in the football. As long as arsenal will still have some guys who have ability to replace him and the club shall not feel worry about that.
Im sure that if arsenal will come back stronger. I have heard that if arteta will not be using havertz in the upcoming match.
