First off, no-one talks like that.
Second off, Villa bought 13 players for that money man.
Third off, yes, €100m does buy a Richarlison. It buy a shit tonne of players, sometimes even 2 or 3. This Summer:
Hazard £88.5m, Pepe £72m, De Ligt £68m, Hernandez £68m, De Jong £65m, Rodri £63m, Jovic £58m, Cancelo £60m, Ndombele £55m, Fernandes £45m, Tielemans £40, Lozano £34, Manolas £32,
If could've got you Ziyech and a host of other players.
Yes the market has changed and yes it's much more expensive, but getting rid of a striker you don't want and spending 214m euros in 10 months as permanent manager is still a shit load of money and if used widely can massively change your team.
