MANCHESTER, England - Striker Robin van Persie insists he is yet to hit peak form despite making a sparkling start to his Manchester United career.
Van Persie has scored 13 goals in 19 appearances for United since his STG24 million ($F68 million) pre-season move from Arsenal, but the Dutch star had some bad news for English Premier League (EPL) defenders on Friday as he admitted he isn't fully happy with his performances.
The 29-year-old has helped United to the top of the EPL ladder, but he believes he can still deliver more goals and assists, starting in Sunday's classic derby showdown with title rivals Manchester City at Eastlands.
"When you are wanted by everyone, it gives you wings," van Persie told MUTV.
"I am happy here and everyone looks very happy to have me here. But I am not satisfied. If you look at the stats, 13 goals in 19 games, it is OK.
"But I want better and more. I want more goals, more assists. I want to go for everything that it is possible this year."
United hold a three-point advantage over second-placed City, but their bitter rivals will replace them on top of the table with a victory on Sunday as they have a superior goal difference.
And van Persie acknowledges United's poor defending this season has to improve if they are to keep ahead in the title race and also thrive in the Champions League.
