We simply don't know what Tiger wants as no detailed plan has been put forward. However, you can argue that there are signs of all.
1. Tiger has invested in the youth and buying players that can develop and increase in value in order to off set ongoing losses. Peterborough and others run this model fairly successfully whilst bobbing around the top half of the league.
2. The ambition is for promotion (according to recent comments from Tiger, Erick, Fosu etc). This would raise the value of the club for future investmnet in no.1 or to sell on.
3. We have various billionaire train set owners of our own. They are currently taking the hit and would presumably want promotion or stadium development to bring the success they want. Although PL would be the ultimate goal, there is still significant interest in the Championship, particularly in the far east.
4. We currently have no assets and any future assets would have to be funded first before being stipped back. Of course there is the danger that they could do what Kassam did, but this is where it is important to agree a substantial and fixed cost lease that allows the club to play for years to come. That is basically what Erick did at DC and I would imagine is what the plans are for Oxford.
