3rd placed teams in the Champions League group stages go into the Europa League. I was thinking, assuming an average Champions League team, is it more worth it (purely financially speaking) to go into the knockout stage (and risk getting knocked out at the next rounds), or drop down into the (potentially easier) Europa League and possibly go all the way to the final / win it?
Winning the Europa League has the ultimate reward as a spot in the following year's Champions League which is also financially rewarding in itself.
