You have an option of parking at Carrefour / Endah Parade. 24-hours parking, and within walking distance to the stadium.
RM1.50 flat fee weekdays, RM2.50 weekends. But it's very hard to get out after the game due to the exit bottleneck. We got stuck in there for over half an hour after the Arsenal game. If you do park inside, recommended to go makan first and let the traffic subside.

Alternatively, you can park around the petrol station area, or go further inside the housing areas.
