It's like 10 million. You can't do shit with 10 million.
Now if Napoli went through and all Italian teams advanced to the next round = more prestige for the league = better tv deals = better sponsorship deals. So would you like 10 million now or 20 later in a better league? Why do people not see this?
It won't make that much of a difference. Napoli would gain more money in the CL, but if we consider coeff, situation won't change much. They might even win more points in the EL. I wouldn't want Italian teams to get knocked out every year, as it would have some repercussions in the long run, but one team more or less is irrelevant. Not worth giving too much attention IMHO.
Italy already has a great TV deal, 2nd best in Europe and that's mostly due to the demand on domestic market, CL doesn't have any bearing.
