The Holland international stole all the headlines on Sunday, with his injury-time free-kick giving United a 3-2 victory over rivals City at the Etihad Stadium to send them six points clear at the top of the table.
It was his 14th goal in United colours this season, while his strike partner on Sunday - Wayne Rooney - has scored four in his last three games to take his tally for the campaign to seven.
Van Persie though was quick to praise the attitude of United's other two forwards, Danny Welbeck and Javier Hernandez, for their professional attitude to training even when not in the side.
He believes that the healthy competition between the four goal scorers will spur them all on to greater heights and is something that rubs off onto the rest of the squad.
"It goes both ways - I can learn from them as well," Van Persie told the club's official website.
"For example, I love Chicharito's [Hernandez's] enthusiasm, I love how he plays and trains and does his work off the pitch after training.
"A couple of weeks ago he wasn't playing as much but he was in the gym every day doing extra work, and that sets a big example for everyone.
"Danny, too. He's not playing in his favourite position at the moment but we need him and he's working hard. When you have four strikers being so professional, it sets the tone for the others.
"Everyone realises we are all in it together and we all need to do our bit."
