Mexican winger Pablo Barrera, who impressed in South Africa this summer, arrives for a fee in the region of Ã‚Â£4 million from UNAM Pumas, on a four-year deal.
Lyon striker FrÃƒÂ©dÃƒÂ©ric Piquionne has also signed for the London club. The forward played for Grant while on loan at Portsmouth last season, and has signed a three-year deal.
Piquionne and Barrera are GrantÃ¢â‚¬â„¢s second and third signings since taking over at Upton Park after Thomas Hitzelsperger was the first to arrive on a free transfer from Lazio.
French international Piquionne said: Ã¢â‚¬Å“IÃ¢â‚¬â„¢m coming to work hard for the squad and to play better than I have ever played before.Ã¢â‚¬Â
Barrera, who made three substitute appearances at the World Cup, said: Ã¢â‚¬Å“I have been really taken by the reception I have received from the players and the manager.
Ã¢â‚¬Å“The fans can expect that I will give 100% to succeed for the team and to play better than I have ever played before.Ã¢â‚¬Â
Grant, who replaced Gianfranco Zola, has also promised to make more signings over the next few days.
