I've never tried it before, but is it possible to dramatically lower the contract club owners offer you when your 'contract' is up for renewal.
Sure, if it was real I would try and bleed them for every penny, but as it is completely irrelevant could I re-negotiate my £105,000 a week salary to like £5 and then I'll have extra money in the wages pot for players?
When I've tried this in the past the minus button is greyed out so I could only increase what I was asking for. Bit daft really since you can't do anything with the money you earn. Suppose it's a good indicator of how well you're doing though.
