But he finds the challenge of succeeding Edwin van der Sar at Manchester United far more daunting than becoming the most expensive goalkeeper in the history of the Barclays Premier League.
He said: "I'm not interested in numbers, clauses and prices. Real value is that which you show on the pitch, not what they say you are worth. Money is secondary and while being that expensive is not something I like particularly, what really interests me is how much worth people think I have on the pitch."
De Gea is more concerned with following in the footsteps of 40-year-old Van der Sar who retired at the end of last season.
He added: "That a team like United think of you as a replacement for a goalkeeper as strong as Van der Sar is great, but I have to keep fighting and working because I'm just at the start of my career and to get to his level will take a lot of effort.
"Hopefully I will still be playing at his age. You need strength, luck and to take great care of your body, because football consumes you."
