West Ham appear to be eyeing reinforcements for their front line when the January transfer window rolls around. Manuel Pellegrini is keen to bolster his striking ranks, giving some help to the likes of Marko Arnautovic, Javier Hernandez and Lucas Perez.
Pellegrini has made no secret of his desire to sign another forward, having already had to dismiss reports that the Hammers were eyeing up a move for LA Galaxy forward Zlatan Ibrahimovic.
A more realistic alternative could come from the Portuguese top flight. According to reports, West Ham are eyeing up a move for Benfica forward Nicolas Castillo.
