this is news that from what i can see it is still not 100% sure how many months he will actually be without playing, according to espn.com, they said that according to a source from them in brazil gabriel jesus will stay 3 months without playing, but that Arsenal had only said that the surgery was a success and that everyone in the team was rooting for him to recover quickly

but we all know that when a politician goes public and downplays a problem that people fear is something serious then we all know that the politician is lying, in the case of soccer teams the same thing happens, probably the arsenal is hiding it information so that your opponents do not know the real state of your player, maybe even gabriel returns to play earlier or maybe he returns to play later, this is also part of the arsenal strategy


I hope he doesn't make these trial and error games against troublesome teams, for example the next game against Brighton, bookmakers are giving odds of @2.00 for Arsenal in case of a win but looking at Arsenal's current scenario it even seems like a good chance to bet on Arsenal, but Arsenal's coach can't afford to do any kind of experiment in this game, because Brighton are playing at home and they are a team that after having gone through a bad phase they recovered, and in 5 games they had 3 wins and 2 losses, arsenal will not have an easy game against Brighton
