It's an absolutely massive change in tack, that's for sure. It's either for the reason you've stated or simply because he has categorically lost interest altogether and couldn't give a solitary fuck any more. Doubt it's anything to do with the Joelinton thing; it's not as if that transfer was based on footballing motives.
You're watching too many Steve Bruce pressers.
Nah, in seriousness, I think Ashley not giving a fuck anymore still wouldn't mean he just allows Bruce and the Steve Mensa Meeting to have carte blanche. It's a business asset of his and he'll want it ran lean and efficient and making money where possible.
I'm hoping he's ratifying these signings as they'll likely keep us up, pootling along in lower mid table another year, despite the best efforts of the management team, whilst he can get the thing sold.
