well its always a conversation topic when teams have to play several games european and national leagues games back to back; players get hurts etc. also when they are call to play for National team and continue in league play its very tiring too.
but hey its modern football;more conditioning,more pampering at the club;and a whole lot more money than ever before!
Platini has suggested and he won on it to reduce the number of teams in the champions but give chance to smaller leagues to get in. Alex Fergunson has been critical of that and so am I.I think they should bring it back to before;only the champions maybe second place teams and thats it. then do the similar cup In UEFA, next 2 going at it. Will be more competitive less games but of course the big advertisers will be bother and less money out.
So its going to be a long road before any changes are made;lots of infighting at the top of FIFA/UEFA circles.
