West Ham is close to a deal to acquire Enner Valencia from Pachuca of Liga MX.
Valencia scored 12 goals in 17 appearances for Pachuca.
Ecuador crashed out of the World Cup in the group stage, but Valencia starred there as well. He scored a trio of goals, including a brace that led Ecuador over Honduras 2-1.
The fee could be close to the club-record $25 million price West Ham paid for Andy Carroll.
