however, Arteta will bring in a centre-forward who is better prepared for Arsenal's upcoming games.
IMO, the player who is ready to replace Jesus is Victor Osimhen. he will also make Arsenal's front line sharper. however, I'm not sure he would want to join Arsenal even if for example Nopoli would approve. But, as a Gunners fan. I hope Arteta will make the best decision for his squad, ahead of the Premier League restart.
I don't sure with Victor Osimhen will replace position leaving by Gabriel Jesus because he has great potential playing on top level team, ever rejected with Manchester United offering and Arsenal is not the priority for Napoli's center forward. Actually bad situation faced by Arsenal right now during they have top performance in Primer League and loss their main player with several weeks later domestic league begin.
Arteta should looking for new player for replacing Gabriel Jesus position trough not any potential reserve player in Arsenal squad right now, have several weeks preparing when window transfer open and Arsenal can compete in Primer League with Manchester City at position standing.
