Just a note: Analyzing the latest Juventus financial statements, I calculated current OCF at ~80MM, and when you consider net working capital (instalment payments due in 1 year), you get an outflow of -35MM, which brings you to operating cash-flow available at ~45MM. Let's assume that because of the UCL revenue different less revenue increases YoY, there is 10MM less in OCF in the next 12 months. That brings you to 35MM in OCF. Also, there is 40MM in cash on the balance sheet.
The thing that this 35MM doesn't consider is the Coman, and Morata potential sales. Those are options, and clauses so this isn't going to be included in working capital. That is potentially a 58MM increase in OCF in the next 12 months.
That means potential OCF of 93MM + Cash of 40MM. That is certainly enough cash to conduct a good mercato, especially when considering Beppe's deals won't involve immediate cash outlays.
