West Bromwich Albion manager Alan Pardew has claimed that football is "losing the plot" due to the current state of the transfer market.
Over the past six months, four players have moved clubs for fees upwards of £100m.
Neymar's £200m move from Barcelona to Paris Saint-Germain in August broke the world transfer record, while Kylian Mbappe, Ousmane Dembele and Philippe Coutinho also moved for triple-figure fees.
"It's difficult with the prices now to gauge what's good value," Pardew told BBC Sport.
"We live in a hyper-inflated world because of the TV money received by the football clubs. Therefore, transfers and wages are going way out of kilter with real life.
"I think we're all losing the plot with the figures. It's just becoming, 'Oh okay,' and not even reacting to things any more.
"If you are a fan of British or European football, you would have a concern about how much money is actually being paid outside of the game."
Prior to Neymar's move, Manchester United's £89m acquisition of Paul Pogba from Juventus in 2016 was the most expensive transfer in the world.
