West Ham United striker Enner Valencia is reportedly a transfer target for Premier League leaders Chelsea.

The Ecuador international joined the Hammers from Pachuca in the summer and has impressed during his first campaign in England.

According to The Express, Chelsea boss Jose Mourinho is an admirer of the 25-year-old's versatility in attack and will launch an official offer at the end of the season.

Valencia, who has netted 11 times in 17 caps for his country, has only scored three league goals for West Ham this season, but has been forced to operate in a wide area over the last couple of months.
