Glazer's loan situation means, by all accounts, that the club will be expected to increase its profitability.
Football (soccer) is definitely on a major up in the US and if Glazer intends that ManU's extra $$$ will come from the US then all well and good.
However, the fear is that ManU negotiate separate TV rights for themselves outside of the Premier League's TV rights. If this happens then no doubt Arsenal, Chelsea and perhaps Liverpool, Tottenham, Newcastle could do likewise but the rest of the league would get diddly-squat from future TV rights.
The current two-tier Premiership is bad enough. Individual TV negotiations would spell the end of UK football as we know it.
By comparison, the future of Ferguson and Keane couldn't matter less.
