Whether or not the club as a whole is for sale, we can't take DJ Space Cadet seriously, and nor do the Lewis family, judging by the tone of their off-the-record media briefing.
If reports are to be believed, it appears that ENIC are up for someone taking a minority stake (10% or 15% maybe?), and this could be someone fitting the multisports profile. The Golden Possibility for all concerned might be an NFL investor who could work with Tavistock/ENIC/Spurs on buying a possible franchise that could have a base in London.
That would be many steps away, and folks here who know more about the gridiron business might be able to advise on how 'possible' this really is.
But it's also the case that a serious NFL-based investor could have their eye on EPL soccerball. With Spurs changing the wage levels and structure by means of short-term, sustainable operating losses, and aiming to punch their financial weight on the pitch, this could be a very good investment.
My sincere hope is that, whoever the investor, the price of a stake is valued not Levy old-style but instead more attractively (10% = e.g., £300m, 15% = £450m?), first; and, second, will involve a share issue, with the money coming in as a capital injection for the football club to invest. I guess the Lewis's would have to take a short term hit on paper from the dilution, but would gain significantly in the medium to long term. But people on here with expertise in this area might be able to advise.
I guess this kind of possibility – if it is at all plausible – might be taken into account in any discussion about whether the Lewis's are in it for the long(er) haul?
