Playing in front of their home fans for the millionth time, Arema knew what they needed after Barito Putra's surprise draw with Perseru.
Cristian Gonzales scored the only goal of the game to set up a final with, umm, someone.
On the morning of the games in Malang it had looked like Barito Putera had the slight advantage but I guess a final with Kalimantan teams played in East Java won't pull in the fans.
