This is where the 'management' part of Football Manager comes in to play.
As things currently stand, you're ******. I assume you have a squad of superstar players with yearly wage increase clauses, high appearance fees, goal bonuses and so forth. While players like Stevie G may be irreplaceable, your players like Cole and Kuyt are not. And they're earning what, 80-100k? That amounts to 640-800k/month. If you're losing 7m/month, cutting two players like that loose will cut your losses by about 10%. Bring in young prospects - you know which ones are good, you know which ones can cover their positions. They'll probably ask for wages of up to 50k, lower appearance fees, lower goal bonuses etc. You'll really slash your running costs by bringing in the young kids.
You could also have more squad than you can support - so get rid of surplus players. I know it's great to have depth, but you don't need 6 DC's just because 'they're all good', or 'what if someone gets injured?'. I've had that problem - just exercise some discipline in the transfer window and use kids from the youth system to cover up for the guy who's covering for your regular DC. Usually won't last for more than a game or so and it gives the kids some first-team experience, which is always nice - especially if they're hot prospects.
Also, attract fans. A full Anfield will bring you in nearly 800k. The better your results, the greater the attendance. Also, better performances mean more TV revenue. If you build it (an awesome squad), they (people with money) will come. Continental competition also always brings in lots of money - expect merchandise, match day, TV and ticket revenue, as well as prize money, to fatten the account.
Most importantly, though, is to keep your squad bill under check. Take into account how much the club is earning NOW and adjust your squad's wages to meet that figure. No point in counting your chickens before they've hatched, or you could end up like Leeds Utd.
