We nearly went broke not long ago, it is hardly weird to think we should try and become a sustainable club. For every example of a club who has recouped equal money spent on their signings after relegation there are 10 that didn't.
Kante was a bargain for Leicester, this is an example of a club paying the upper bound of what a player is worth (probably in wages as well) so that he joins them and not a better club. I would be happier if we don't do that.
