The 27-year-old joined the London outfit from Spanish club Real Betis in the summer of 2013 and has been one of the best players for the Hammers this season.
“I am a person who has clear ideas and I know I need to work hard in every game and every training session,” Adrian told West Ham’s official website.
“Whenever you get a chance to perform, you need to give 150 per cent because people are watching you and you need to show them you are a really good player.
"As a goalkeeper, it is even more important because if you make one mistake, they say a goalkeeper is bad.
“You can make 30 saves, but people remember your one mistake. You need to stay concentrated 100 per cent for the whole 90 minutes and to show a good approach.”
With West Ham flying high in the Premier League at the moment, much of the plaudits have gone to the attackers and the midfielders.
However, Adrian’s significance in that success cannot be undermined. The Spaniard has kept three clean sheets and has made over two saves per game on an average.
West Ham are back in Premier League action today when they take on Leicester City at the Boleyn Ground.
