The Hammers secured their first signing of the summer last week, as Fulham right back Ryan Fredericks joined the club on a free transfer at the end of his contract.
With new manager Manuel Pellegrini no doubt expecting considerable investment, more signings are expected, and West Ham are in need of another creative player.
Joao Mario has returned to Inter Milan after the expiration of his loan deal, whilst Manuel Lanzini faces a lengthy spell on the sidelines having suffered a major knee injury with Argentina.
One of the main names linked with West Ham so far is Lazio wide man Felipe Anderson, but Football.London report that the Brazilian wants a major wage increase to make the move.
Anderson allegedly earns around £48,000-a-week with Lazio, but would demand around £80,000-a-week in order to join West Ham, and it remains to be seen whether the Hammers accept those terms.
Anderson, 25, starred with Lazio following a 2013 move from Santos, earning interest from some of Europe's biggets clubs, but he has somewhat stagnated in Italy, meaning West Ham have a legitimate shot at his signature.
With eight goals and eight assists this past season, Anderson still has great quality, and in light of Lanzini's devastating injury blow, the Hammers may be wise to meet Anderson's demands in a big-money deal.
