Yes, If you read the op, The head of the German FA has already rejected the notion and he believes that the rest of the top 5 will also reject it. However this is reportedly being supported by both FIFA and UEFA. UEFA will have influence over some of the smaller league nations and they can change the dates of friendlies and the European competitions if they so feel. Do you think the top leagues will be happy if they miss players for intl friendlies and the CL gets messed up?
Also I dont think it will happen either but its just the notion that FIFA want to do this is making my blood boil just to appease the decision of the 2022 WC. FIFA dont care about the good of the game and this is just the latest mad cap idea they have had.
surely teh teams would refuse to release the players, and if it happens i'd love to see it change before 2018 as it would be funny watching the world cup in the middle of a russian winter.
