Inside the prem:
Batshuayi - He'd be my Ideal candidate. Got the pace we need, and could be a good loan option if Chelsea don't want to sell.
A couple I'd look at outside the Prem:
Kevin Gameiro (Athletico) - Would love him here. Pacey and Dynamic.
Babacar (Fiorentina) - Not going to set the world alight, but an absolute improvement on Niasse.
Bas Dost (Sporting) - Looks to be in the form of his life. Sporting wouldn't be able to turn down 45m.
Anthony Modeste (Tianjin Quanjian) Think he might be on loan from Koln, but would be ideal type of player
Ivan Santini(SC Caen) Big Lump, who could come good.
Cedric Bakambu (Villereal) - Long shot.
There's a lot of talent out there, I'd like to see us cast our nets a little bit further than someones bench or pay through the nose for a Troy Deeney/ Benteke type. Honestly, If someone of any real quality isn't available, go for an Enner Valencia-esque loan player as backup and stick with DCL, as he's doing a brilliant job.
