(Reuters) - Liverpool manager Juergen Klopp has slammed the idea of a World Cup every two years, saying the proposal was nothing more than an opportunity to generate more revenue at the expense of the well-being of players subjected to a "relentless calendar".

FIFA's Congress in May voted by a large majority to conduct a feasibility study into the potential of holding the World Cup every two years instead of every four years, with 166 national federations voting in favour of the study and 22 against.
