The club, stadium and training centre are different branches in the ENIC tree now, then there's all the NDP stuff too.
It caused quite a stir within the die hard Spurs fanbase when word got out that WHL which the club owned had been replaced with a stadium they didn't own that was primarily designed to be a permanent home for the NFL in London. In the same interview where that news came out the football club were referred to as 'anchor tenants' which didn't go down well.
Everything is independent of each other, but at the same time it all runs together if that makes sense. But to be honest it's all beyond my knowledge of economics and business so I haven't looked into the finer details.
None of that is relevant to the FA cup thread though as we didn't even bother turning up for that!
