FYI, Thohir's Mahaka Group is backed by Salim Group as several other prominent Indonesian businessmen. Not exactly sure whether they were involved in the deal, but their backing-up should be a guarantee for Thohir Group's financial power. Not only that actually, our nation economy is growing (despite wealth inequality), so we may be able to enjoy the support in foresseable future.
Nonetheless, there's a whole different question over the sustainability of their financial support, since there are only few rational owners who will throw money in a bottomless pit. Just the same reason why people here should pay respect to Moratti, regardless of being his supporters or haters. If not because of his 'irrationality', we would not have been an Inter fan in the first place.
Lastly, I have no idea whether the involved people read this message or not. But, I'll will tell you have a great expectation on you shoulders, not only from Indonesian people, but also any Inter fans in the whole world. It's time to walk the talk. Don't you dare to bring shame to all of us.
