If I invested heavily in squad building and the money was wasted I'd look at that dimly. If, on the other hand, I'd acquired shares only, my interest would be just that the value of them wasn't taking a nosedive. That's not happening, because we are solidly ensconced in the PL and will remain so, and the exposure through games like SFs and the QF coming up - and hopefully Wembley appearance(s) to come - is a boost to the club profile.
As said above: it would be a an incredible position to take if you were a new major share holder if you sacked someone who had a) not wasted any cash of yours, and b ) proven to be adept at stretching cash to acquire a lot of quality players. Utterly incredible scenario.
And by the way, the value of the current squad must have also been a major attraction to him becoming involved with EFC.
