Producing funds from the academy is also very important, but for both financial and just classic Fergie keep the culture fresh perspective you need to be getting full value for an important player every now and again.
Mane from Liverpool, Alvarez from City, this is the way.
Letting the Poch team go so stale by refusing to be a "selling club" was a mega miscalculation that we're only now digging our way out of.
Poch knew this and Levy wouldn't listen.
Mate... Duran is a 21 y/o prem quality striker who had a bright future.
Not remotely the same thing as Klopp letting go of Mane aged 30.
...........Selling Duran wasn't about refreshing old parts; it was cashing in before a likely boom. If anything; the above suggests selling Watkins instead was the smart (Mane, Kane) move.
