Don't let Donald Trump's tax plans fool you. In football, trickle-down economics can be a positive thing.
In 2013, when Tottenham sold Gareth Bale to Real Madrid, the money they received was redistributed via the purchase of Paulinho, Nacer Chadli, Roberto Soldado, Etienne Capoue, Christian Eriksen, Erik Lamela and Vlad Chiriches.
So Madrid's money trickled down to Corinthians, FC Twente, Valencia, Toulouse, Ajax, Roma and Steaua Bucharest: seven clubs in six countries.
Looking at the transfer activity of those clubs that summer, Tottenham's largesse then trickled further to Cerro Porteno, Coimbra, Penapolense, Ponte Preta, Londrina, Monterrey, Ajax, PEC Zwolle, Valerenga, Volendam, RKC Waalwijk, Cruzeiro, Real Zaragoza, Rubin Kazan, Vitoria Setubal, Napoli, Chelsea, Levante, Legia Warsaw, Sporting Gijon, Hercules, Red Star Belgrade, Esbjerg, Young Boys, Utrecht, Heracles Almelo, PSV Eindhoven, Udinese, FC Vaslui, Otelul Galati, FC Viitorul and CFR Cluj.
