American international Graham Zusi is reportedly undergoing a trial period at Premier League club West Ham United.
The 26-year-old, who currently represents Sporting Kansas City in Major League Soccer, is regarded as one of the best talents in his home nation.
A number of European clubs have registered an interest, according to Sky Sports News, but the Hammers have taken the attacking midfielder on a trial basis.
Zusi, who will spend a week at the club, has three years remaining on his deal with Sporting Kansas.
