Well it might not be good for his career, but it certainly won't do his bank balance any harm.
And don't forget the £87m they paid for Mykhailo Mudryk when they snatched him from under our nose earlier in the year (I'm beginning to wonder whether we actually dodged a proverbial bullet, there).
They have spent an astonishing - stratospheric - sum of money over the course of the season.
Potter wasn't given time (granted, no Chelsea manager ever is, these days); I'm glad that his payout will numb the pain, and, as you so rightly remark, his bank balance will be exceedingly healthy as he contemplates the state of being without gainful employment.
