5) West Ham (-€435m)
The Hammers have rocketed up this list over the past year after a lavish spending spree during the 2022 summer transfer window.
Significant outlays on Lyon’s Lucas Paqueta, Sassuolo’s Gianluca Scamacca and Rennes’ Nayef Aguerd have been made but results haven’t followed.
As a consequence, manager David Moyes is under huge pressure, with West Ham currently sitting 17th in the table.
