Enner Valencia has criticised West Ham United's medical department by claiming that the club have refused to let him speak to another doctor.

The 25-year-old has been out of action for a month since suffering a knee injury during the Hammers' 2-2 draw against Astra Girugu in a Europa League qualifier.

The Ecuador international has hit out at the club for not "supporting" him and insists that his injury has not been properly diagnosed.

"West Ham seem to have forgotten that I'm injured. But they don't let me speak to another doctor. I don't understand why West Ham doctors are doing this to me," Ecuador radio station La Deportiva quotes Valencia as saying. "The truth is that West Ham have not been supporting me.

"I have tried to ask an external doctor but the doctor of West Ham doesn't want me to ask another doctor. It's my health we are talking about here. I have been injured for a month and I still don't know what the name of my injury is."

Valencia joined West Ham last year for a reported £12m fee.
