document: The Hammers have had one bid rejected for the 25-year-old, but manager Slaven Bilic is hopeful of concluding a transfer.
  Carvalho was part of Portugal's triumphant Euro 2016 squad and also featured in their third-place finish at the Confederations Cup this summer.
  He has scored one goal in 37 international appearances.
  Bilic signed forwards Marko Arnautovic and Javier Hernandez, for £20m and £16m respectively, and goalkeeper Joe Hart on loan this summer.
  However, a side containing Hart and Hernandez lost 4-0 at Manchester United in their Premier League opener on Sunday.
  Sofiane Feghouli has joined Galatasaray for a reported £4m, after a season at the Hammers.
  The Algerian winger scored four goals in 27 appearances, after joining from Valencia in June 2016.
summary: West Ham are closing in on the signing of Sporting Lisbon midfielder William Carvalho for an expected £30m.
