To a greater or lesser extent; every deal is subject to wages, agent fees and extras too.
(Can't remember when now; but not so long ago Man U were reported to have spent near 100m on agent fees alone in one year!)
.......Do the above figures include loan fees for all the respective clubs? ........Any other player-related financial quirks? I shan't pretend to know; but as is typical, once one start's pulling at the threads of any 'easy hit' set of figures; the complexity of the true picture renders them rather superficial (...Not unlike the whole "what window does x player get attributed to" crap-fest when it boils down to actual cashflow, rather than projected annual budgets).
Nah, you're getting that muddled... 50m was trf fee payable to BVB..... The rest of the money you're describing went down the same channel.
Yes, his agent set a low release clause with BVB that allowed Haaland the chance to max out his earning and retain max freedom of movement, but it was never a case of simply "whack it all into wages so the fee doesn't wreck Man Cs FFP from the trf fee end"..... That's just a convenient up-shot.
