Arsenal captain Robin van Persie is promising further improvement next season, despite scoring 32 goals in 37 club appearances this season.
The Dutchman has often ploughed a lone furrow up front for the Gunners, assisting in their surge into the fourth Champions League spot this season.
Van Persie is closing in on on the Premier League golden boot, and the magical 30 goal mark, however the 28-year-old is unsatisfied by his performances this season.
"Even now, I'm still improving," Van Persie told FourFourTwo.
"When you say 'I'm not improving anymore,' you are finished. My heading could be better for example. I've improved but what's the maximum? I'm not going to know until I find out by trying. Yes, I've scored a couple of good headers this season. But when are you satisfied?
"People can say, 'He's scored three headers this year - I'm satisfied with that' but I don't think so.
"Why not five? Why not 15? It never really stops. By saying 'Never be happy,' of course I am happy in a way. I'm enjoying my football. But I'm not satisfied that easily.
"Why not score 10 headers instead of three? I've always been like this. It's a good thing to have in this business. I never expected to score 48 goals in one year like I did in 2011. But now I have done that, I want to score more than 48 because I know it is possible."
Talk of Van Persie wanting to improve on his showing this season hints towards wanting to extend his career at the Emirates Stadium.
The former Feynoord forward is out of contract in the summer of 2013, and is yet to pen a new deal with the club, leading to rumours over where his immediate future lies.
Both Samir Nasri and Gael Clichy left during last summer with just a year remaining on their respective deals, but the club will be hoping to tie Van Persie down to a new deal at the end of the campaign.
