Just for fun, looking at that list I'd say...
Antony - 100% EtH buy
Casemiro 0% Clearly wasn't a managers pick and i'd be interested how you came to that assumption? other than a player arriving under the managers tenure = managers buy?
Mount 0-50%
Hojlund 0-50%% EtH wanted an experienced CF like Kane so I can't see how Rasmus equals a EtH pick.
Onana 100% EtH buy
Zirkzee 0-50%
I'd say De Ligt, Maz, Martinez, Antony, Onana are the clear 100% Managers picks and some of those have been great in spells.
That's the thing with transfers, some you win some you lose.
