The Holland striker took his tally to 31 for the season, which includes 25 in the Premier League, with both goals in Saturday's 2-1 win at Liverpool.
Van Persie was at his clinical best, converting the only two chances he had, as first he equalised Laurent Koscielny's own goal with a close-range header before expertly volleying past Jose Reina in added time to snatch three points.
"I've got 31 goals this season. I can't believe it," he said afterwards.
"It is the first time in a season I have scored this many - and 25 league goals, it is just insane.
"But I have to thank my colleagues because without them I am nothing and they are a massive help."
