Kepa Blanco is currently on loan to West Ham from Spanish side Sevilla.
He said: “My experience in England has been very negative and perhaps I have arrived at the worst moment. It has been the worst time of my career.
“The coach has not had any confidence in me. I work hard every day during training but afterwards I am not in his plans for the matches and he never says why.
“My future depends on Sevilla. I have no desire to stay at West Ham.”
