Champions League
2018: Real, Bayern, Roma, Liverpool
2017: Real, Juventus, Atletico, Monaco
2016: Real, Atletico, Bayern, City
2015: Barcelona, Juventus, Real, Bayern
2014: Real, Atletico, Bayern, Chelsea
Over four years (2014-18) we have four different finalists. Over two years we have 7, 6, 6 and 7 semi-finalists. I thought there would be more overlap in the latter. Could 6-7 European teams be included in a 16 team tournament? On quality, yes; on TV money, yes; on FIFA politics, no. Which wins, money or politics?
Copa Libertadores
2017: Gremio, Lanus, Barcelona, River Plate
2016: Atlético Nacional, Indepentiente, Sao Paulo, Boca Juniors
2015: River Plate, UANL, Guarani, Internacional
2014: San Lorenzo, Club Nacional, Bolivar, Defensor Sporting
Far less overlap, with only River Plate makes the semi-finals twice in four years. So four or eight teams are easy to select.
