West Ham are keeping tabs on Brentford striker Ollie Watkins after failing to sign him in January, according to The Sun.

Watkins has scored 22 goals for the promotion-chasing Bees this season and is likely to become the latest in a long line of talented players to leave Griffin Park this summer.

The Hammers were unable to prise him away in the winter window but are priming themselves for another bid this summer.
