Gabriel Jesus is official and this is a new force for Arteta with Arsenal who will make the competition even more competitive in the near future, but I'm sure there will be good changes that Arteta will work on with Arsenal.
However, we will see that the transfer window still has time so that Arteta can bring in a few more players, but this is a transfer that has been highlighted a lot because he has managed to sign Gabriel Jesus at such a young age.
He is a good player but I don't think he should be even worth that much. He only scored 12 goals last season and all competition combined so that's not really that impressive. Also that Manchester City has the best midfielders squad that could supply him with great assist so I don't know if he could do better in Arsenal
