Reading through this thread, Superhudd comes across quite poorly at times but I think I understand what he is saying and it does make sense:
If Lewis invested £200m with Spurs, he would get multiple paybacks - i.e. Spurs would pull in way more money per game, some of which could go back to Lewis to pay him back, the rest of which would be reinvested in Lewis' team/investment i.e. Spurs, so it is win-win.
If Lewis invested £200m in shale mining or whatever, he would also get a payback.
But investing in Spurs would not be so ludicrous, it would pay him back, it would turn Spurs into more of a force, and we might crack into the CL and pay him back BIG time, so it is a good way for him to invest some money.
I think saying Lewis is a waste of time and should bugger off is way wide of the mark, but I do think he could invest in Spurs legitimately to improve his own company/portfolio and see a return on it.
PS - in terms of players when I see Bentley, Gallas, Florent Malouda, Eric Lichaj, Schwarzer, Arshavin, Dunne etc. released for free I do fully understand why Levy wants to get younger players with a hunger AND a sell-on fee.
