Roberto Mancini, manager of Manchester City, for instance, said Van Persie could decide the title in United’s favour and so it has proved. Whether City were ever in competition for his signature is debatable.
Sir Alex Ferguson told confidantes two years ago that Van Persie was the one great player left at Arsenal and that he could get him at any time. Seeing the title go to City last season might have crystallised those thoughts.
Last night made the logic irrefutable. Van Persie destroyed Villa and, in doing so, steered United over the line at a trot. Nobody wins the title waving and throwing roses to the crowd. United, however, went close.
It helped that United had several swings at getting the three points required, not just this one, but even so Ferguson looked uncommonly calm prior to kick-off, still signing autographs after the match had started. He put his pen away just in time to see United take the lead.


Antonio Valencia carried the ball down the right and laid it back to Rafael, whose cross at first appeared to have been hit too deep. The curl on the ball kept it in and Ryan Giggs played the ball back across goal for Van Persie to tap it in from close range.
The celebrations began from there.
It was party time at Old Trafford, a surprisingly rare occasion considering this is Ferguson’s 13th league title.

It was a masterful finish, precisely what a fee of £24million is supposed to buy — what Chelsea thought they were getting for £50m from Fernando Torres.
The tradition will see Arsenal forming a guard of honour when Manchester United visit in six days time. It will stick in the craw to salute the former captain who deserted their cause, but no player will deserve it more.
Indeed, as one prime candidate withdraws from the running for Footballer of the Year, so Van Persie reacquaints us with the identity of the most influential player this season. Luis Suarez and Gareth Bale have turned in magnificent individual displays for Liverpool and Tottenham Hotspur, propelling their clubs forward, but Van Persie has defined the title race.

United lost the title last season on goal difference, never forget, and it is Van Persie who has ensured there will be no repeat of that embarrassment for a team usually so prolific.
