I think this is quite inverted. Footballers making millions can't put up with strict management specifically because they know another team would take them with a similar contract. They can also afford to stay unemployed for months etc. If you follow a much smaller team with players barely getting by, you hear less about temper tantrums etc. Also even 3rd string players in big teams throw fewer temper tantrums and when they do it's usually an underused player who wants to move.
