As someone who works in investment management and looks at companies for a living (security selection for a private wealth management company), I've looked at Juve's financials... They aren't great, but solvency isn't in question. The company is pretty much break even, and without transfer market purchases actually makes money (ie: no signing, just carrying the wage load). It's ISN'T extremely profitable by any means, and I'd never ever invest in it's equity. However, considering I specialize in high yield debt (aka junk bonds, non-investment grade bonds like Radioshack, WIND Telecomunicazioni) I wouldn't hesitate to lend money to Juve (I'd want a 7-8% coupon), but I would.
That brings me to the assertions of the English media that we 'need' to sell Vidal for financial purposes. That is a absolute crap. The only issue the company may have is liquidity, with large payments due in the near future. That can be covered with a line of credit, because its liquidity, not solvency. All Juve needs to focus on is investing wisely, and growing revenues - selling players isn't imperative unless the proceeds are that significant and the targets are both attractive and attainable.
