Of course, I think he needs more experience and training hours. He is still young, his career is still quite long. I don't think it has to be in the EPL where he is needed and gets a suitable offer so I think he should take it. It takes time to be great, so does the coach. Although he is a great striker when he plays, everything is different when he is a coach. Being a coach is very complex, he has to be able to control all elements in the team. Get out of the safe zone, take as much experience as possible. I think he will be interested in big clubs if he has good performances.
Training is important. Profession is important too. Time is very important for any player to start and adapt to a new club. Very few players can succeed in very early time after joining a new club. Some players have good debuts and honey moon but then lose position. Adrian Mutu in Chelsea in early years of Abramovic and Morata in Chelsea recently are examples.
That is the high professional attitude that Gabriel Jesus has, not many players can accept not playing in the Champions League. Because if I consider, choosing Arsenal as his new team is a setback for him. But if Gabriel Jesus really wants to play as a main player in every match, then Arsenal is the right choice, it's just that for the Champions League place can not be guaranteed because the EPL team competition is not as easy as imagined.
Gabriel Jesus had to change himself and got a position in Manchester City but he did not play like a real striker. Manchester City after failures in Champions League need to find a really good striker. They bought Haaland and Jesus will have a very uncertain future. He can not compete with Haaland for a striker position and in midfield, Jesus can not compare with Riyad, Foden, Bernardo Silva, Gundogan, De Bruyne. He has to leave and choose a club that can help him to play regularly. It will help Gabriel as a slot in Brazil for the World Cup.
