Many has good experience of playing in different top leagues which is helping them for having some positive improvement in game and Indonesia is having good squad but still it's not near as few countries for challenging them if they can do this consistently then surely in near future they could be able to win this trophy but right now in 2023 its not looking better chance for them to win this trophy from few giants of Asian Soccer.
As an Indonesian and Football fans, I think the chance of they doing it consistently in long term is very small , the team performance are very dependent on how the local competition going, and quality of the competition depend on how the federation handle it. And there are a lot of corruption in the federation and in the competition in the past years, we have a good year in 2017 with Luis Milla but in only 1 year the federation kick him off, for some absurd reasons.
The local players will not be a problem if we have good league tho, but I agree that for now the best option is to find player who plays overseas, with better league and competition.
