"Football is for moments and now I am playing well so I hope I can continue like this and help the team as much as possible," said the Spaniard.
"Last year, up to December, I played really well and then I don't know why I dropped my form.
"Now I've started to do it again and it is more important to think in the present and live from now and I will try to do my best now.
"To be honest I've never been worried because I've always believed in myself.
"From the start I had knee problems so I have to prove myself with the manager; you have to do that always.
"It is not what you did before, it is what you do now. Every time you have to play well - if not there are players who will play better than you do.
"But I am really happy here. It is the biggest club I've played for, the fans are amazing and I really like the city so of course I want to play here for a long time."
