Adrian told WHUFC.com: “This is a proud moment for myself, my family and friends and I am really happy to have signed my second contract with the Club. I feel really happy for the Club and the fans.
“I never imagined this kind of relationship with the fans. I spent 16-years at Real Betis and it was difficult to leave your home.
“But from the moment I arrived in London the West Ham fans had a special relationship with me.
“For me this is a really good moment and I just want to enjoy it. This is my third season here and I want to stay here for a long time.
“Next season is really important for the Club. I have enjoyed playing at Upton Park and I want to enjoy playing in the new Stadium. It is a big step for the Club and I am really excited about this moment.”
