The 27-year-old has failed to impress since joining the Hammers in 2014 and the Premier League outfit have now decided to cut their losses.
According to Sky Sports, West Ham have agreed on a fee with Tigres for the striker. The Ecuador international will cost around £6-7 million.
Valencia has scored just 8 Premier League goals in 54 appearances for the Hammers and it is quite understandable why West Ham are ready to get rid of him now. He spent last season on loan at Everton and scored a total of 3 goals in 21 Premier League outings.
