But that's because they accumulated their team expensive stars years ago so haven't need to buy them again recently - just sporadic refreshing. Take inflation into account and they've got fourteen players in their current squad that cost at least 50m euros. (Marmoush, Gvardiol, Nunes, Doku, Haaland, Phillips, Grealish, Dias, Ake, Rodri, Walker, Silva, Stones, KDB). And then take into account all the other big money players they've bought ages ago and then, for quite a lot of them, sell and use those funds to shout out about 'low net spend' (Sane, Jovetic, Dzeko, Sterling, Otamendi, Jesus, Mendy, Mahrez, Cancelo, Danilo, Torres, Alvarez).
Liverpool have eight current 50m+ euro players (Szoboszlai, Nunez, Diaz, Jota, Alisson, Konate, VVD, Salah).
Arsenal have five (Rice, Havertz, Partey, White, Jesus).
To try and claim some sort of moral high ground of 'look at their low net spend' or 'they've spent less than Arsenal and United' when said team is filled with £1bn+ worth of bought talent is disingenuous.
City have spent absolutely loads and are no doubt going to get no charges whatsoever for doing so. Ah well.
