With deals for Mauro Zarate and Cheikhou Kouyate confirmed, West Ham have turned their attention to Spanish defender, Marcos Alonso.
The left-back spent last season on loan at Sunderland and helped the club to prolong their stay in the Premier League, and reach the Capital One Cup final.
Alonso has settled in England and is interested in making a permanent move to the capital.
His parent club, Fiorentina, are prepared to let the player go and are reportedly in advanced talks with West Ham.
According to the Mirror, the deal is likely to cost West Ham just £1.5million - a bargain for a player who has already shown what he is capable of in the Premier League after spells with Bolton and Sunderland.
Sam Allardyce identified Alonso as a replacement for exiting left-back, George McCartney, who is set to leave the club when his contract expires on July 1.
This summer looks to be a busy window for the Hammers, who look to strengthen after a lacklustre season, which lacked entertainment, according to the club’s owners, David Sullivan and David Gold.
The club have been linked with a number of other signings, such as the Ecuadorian winger, Jefferson Montero and released Manchester City pair, Gareth Barry and Joleon Lescott.
