A rumour that makes little sense. If he is good West Ham would keep him. So unless he is set to rival Jerome Sinclair to start against lower league sides in the cup it's just another bit of tittle tattle. http://www.hitc.com/en-gb/2017/07/03/watford-and-burnley-tracking-west-hams-ashley-fletcher/
In the ocean of twattery that is West Ham I nevertheless get the impression that Bilic can accurately rate a footballer.
This caught my eye at the bottom of that article, Burnley could lose Andre Gray this summer with the player yet to agree a new deal at Turf Moor, while new Watford boss Marco Silva is looking to reshape his squad at Vicarage Road. I know he's an ex-scummer, but then so was Matty Spring, and I quite liked him.
Personally, he sounds very much like a Burnley signing. We've probably lazily been linked as we are a standard, local side near the bottom of the table. I'd have him for a few million.
Still, he'd better have absolutely top-notch ball control for that kinda money. I'd also hope he'd be very comfortable playing with his back to goal, and when needed can get plenty of shots away from inside tight positions.
