West Ham are set to bid £30million bid for Watford attacker Ismaila Sarr.
Boss David Moyes needs a new forward after the sale of Sebastian Haller has left Michail Antonio as their only out and out striker.
Sarr - who can play out wide or down the middle - stayed with the Hornets after relegation and Crystal Palace had an offer for him of £25m plus extras rejected on deadline day.
But The Sun says West Ham are prepared to top those numbers and test Watford.
