On the point about FIFA wanting to make money - it is interesting that they have consistently tried to keep milking the World Cup for more dollars, but haven't made any coherent attempt to do something with their club tournament. At some point someone at FIFA will realise there is a limit to how much can be made from a tournament which runs for one month every four years, and maybe it would be better to work on improving the returns from their annual event.
I've never really understood clubs moaning about fixture congestion. They don't have to enter if they don't want to play, and the coaches should adjust the intensity of his tactics accordingly. Football should be about more than just physical fitness anyway. It's a bit like a small business accepting a big contract to sell its products, and then complaining "hey, you're making us work all the time!"
I'd say the fixture congestion thing is solvable at big club level by sticking their arm in that massive barrel of reserve/youth players they have made huge investments in, must be hundereds in there.
I wasn't following football at the time of that Manchester United's FA Cup / Club World Cup debate, but I don't see why they couldn't have just played the FA Cup game with the players/coaches that didn't travel, and on top of that they were only gone for a week
, surely they could have managed or The FA could have offered a less controversial solution (like letting them play on a replay date and the tie be settled on the night), is the point I'm making.
And of course I can't not mention the example of non-league clubs, at some levels they play more games than their high-quality counterparts, and in extreme cases of postponments / cup runs I've seen stories of them playing 5 games in 5 days at the tail-end of the season, not to mention the smaller squads and the day jobs the players often have, while big club will moan at the prospect of 2 games in 5 days...
For your FIFA making money point, yes, the Champions League is the example of how a club competition can become a financial behemoth and having worked with it for so long Infantino probably realises that more than anyone, which is why earlier with my qualification theories I was suggesting the expanded cup could be a yearly summer event rather than a 4-year run as seems to be implied. Even though that could have a World Cup-style 'event appeal', a key reason for the CL's financial success is regularity, so something running throughout the regular season like a Cup Winners Cup could be FIFA's ticket.
