He's surely the complete opposite of that though? He's cost relatively little and has proved to be able to contribute in forward positions in this league, its quite low risk and an improvement on what we currently have.
What got us in this position is lashing stupid money at Sigurdsson, Bolasie, Klaasen, Tosun etc and overloading certain positions with garbage whilst not addressing glaring holes season after season. I don't think anyone is claiming Maupay is a world beater or that they want him leading the line for seasons to come, but he gives us an effective option in a position we need without breaking the bank.
