Arteta already has a good experience with Arsenal and last season did well despite failing to make it to the champions league, but they have evaluated everything Gabriel Jesus and Rafinha will be brought to Arsenal to strengthen their attacking line they are sure that next season will be tough competition but Arsenal can overcome it all from its previous slump.
Gabriel Jesus is a great purchase. If they get Raphinha, and Lisandro Martinez who they've also made abid for today, then it will be a solid transfer window for them, and I'd expect them to really push for that Champions League spot next season. Don't know what the likelihood is of them getting all three, as obviously other clubs are interested too, but Gabriel Jesus is certainly a great start.
