While I can’t disagree with the above, you aren’t comparing like for like periods and specifically the stadium build era until around 2013.
If you look at Wenger, he spent alot post 2013, when Fergie was retired and other managers were spending at old Trafford. Likewise Wenger started late 1996 so Fergies transfers pre Wenger were cheap compared to modern transfer fees.
Yes, if you have broken the rules.
