You said get someone who can score more. Who?
Ivan Toney and Adam Armstrong are two guys I would look at from the Championship.
Edouard from Celtic, Leao from Milan but he is probably more money than the Vini buy clause would have been, Amine Gouri looks like a good young player, Mousa Dembele is someone I would look at.
There are also MF options that would score more goals than he like Periera and Buendia.
