In the past, clubs will nurture young players and send them to the national team trials. There are 5 major clubs in INA: Jaya Raya Jakarta (eg: Candra Wijaya, Markis Kido/Hendra Setiawan, Angga Pratama), Djarum Kudus (eg: Mohd Ahsan, Fran Kurniawan, Mohd Rijal, Rendy Sugiarto/Afiat Yuris Wirawan, Sigit Budiarto, Antonius/Denny Kantono, Eng Hian, Maria Kristin Yulianti, etc), Tangkas Alfamart Jakarta (eg: Simon Santoso, Nova Widianto/Liliyana Natsir, Vita Marissa, Greysia Polii), SGS Elektrik Bandung (eg: Taufik Hidayat, Flandy Limpele, Hendra A. Gunawan), Jaya Raya Suryanaga Surabaya (eg: Tri Kusharjanto, Alvent Yulianto Chandra, Ryan Agung Saputro), and Mutiara Bandung (eg: Ricky Karanda Suwardi, Andre Marteen, Suci Rizky Andini)
But nowadays, we have seen many ex-national team players returning back to their original clubs and they can still contribute by sparring with the young team-mates in the clubs (eg: Rian Sukmawan/Rendra Wijaya) and participating in the domestic circuits (Djarum Sirkuit Nasional or the official national circuit - 9 of them in total every year, and some other domestic tourneys like the Indocock Walikota Surabaya Cup, Pertamina Cup, etc), which have also become more and more active in the past 3 years or so.
Djarum has also set the trend for sending club players to selected international tourneys as has been seen in the recent Russian Open GP and the White Nights Russian International Challenge 2011. Increasingly, clubs like Mutiara, Jaya Raya, and Suryanaga have also been sending players to tourneys like the Singapore International Series 2011.
