West Ham are on the verge of signing Valencia striker Toni Martinez in a £750,000 deal.
The highly-valued 18-year-old has scored more than 100 goals for Valencia’s youth teams and is acknowledged as one of the brightest prospects in Spanish junior football.
The deal is expected to go through in the next week.
“With Martinez, we are quite close,” Bilic said.
“Terry Westley from the Under-21s has done a tremendous job if we finish it and we are close to getting one of the brightest talents from Valencia.”
