He admits: "I used to worry because I was selfish and wanted to be in my favoured position every game - like you do on the playground when you're a kid.
"But the game has changed. I have learned to understand I have a job to do for the team.
"You can't afford to be selfish. If I play out of position and we get a win I still get the same buzz.
"If the manager says to me I'm playing centre midfield or off the front man, there's no massive difference to me.
"But yes, I enjoy playing further forward, especially behind Fernando Torres.
"Last season was probably one of the easiest I've had. The quality of his runs, the amount of chaos he was causing, let me in to get 21 goals.
"I'll play wherever the manager wants me to play and not worry about it."
