The 34-year-old, who won 102 caps for Holland, returned to his first professional club in January following a 14-year absence.
Van Persie scored five goals in 12 Eredivisie games on his return and has now agreed to prolong his stay.
A statement on Feyenoord’s official website read: “Robin van Persie has agreed to add one more season to his playing career at De Kuip.
“The club recently made it known through technical director Martin van Geel, head coach Giovanni van Bronckhorst and others that Feyenoord wanted to keep hold of the striker.
“The 34-year-old has now said that he would like to play for one more season.”
Here, we preview the match in numbers.
12 – United have won the cup a dozen times. They have the chance to draw level again with Arsenal’s record tally, just a year after the Gunners edged ahead on 13.
7 – Chelsea share fourth place in the list with Liverpool and Aston Villa. An eighth win would take them joint third with Tottenham.
9 – nine of the 11 finals since the showpiece returned to Wembley have been won by either Chelsea (four), Arsenal (three), United or Manchester City. The two exceptions, Portsmouth and Wigan, both played in League One this season.
1 – the managers in this year’s final, Jose Mourinho and Antonio Conte, have just one win between them – current United boss Mourinho leading Chelsea to the trophy in 2007.
7 – Wigan’s Will Grigg is the leading scorer in this season’s competition. United striker Romelu Lukaku lies two behind but is an injury doubt for the final.
£1.8million – prize money awaiting the winners, double that of the beaten finalists.
737 – teams who entered this season’s competition, with the first ties played on November 3 last year.
58 – United’s streak of 58 successive televised FA Cup ties, stretching back 12 years, ended when they were overlooked in the third round.

Red Devils boss Jose Mourinho will be looking to get one over his former club, while counterpart Antonio Conte aims to go one better than last season when his side were beaten by Arsenal in the showpiece event.
Here Press Association Sport looks at the main talking points heading into the Wembley clash.
Conte’s position as Chelsea boss has been a constant source of speculation for months, with the Italian cutting an increasingly unhappy figure at Stamford Bridge.
Having delivered the Premier League title in his first campaign at the helm, the 48-year-old was initially unhappy with the summer recruitment drive in west London.
Add to that poor results on the pitch, which led to finishing fifth in the table, and all pointers suggest the former Juventus midfielder will bow out at the end of the season. Winning the FA Cup would be a good way to go.
Mour silverware the aim for the ‘Special One’
Having delivered League Cup and Europa League success in his maiden season as United boss, Mourinho will now want to add the FA Cup to a second-place Premier League finish.
The Portuguese has 11 honours to his name during his time in England, including two stints as Chelsea manager, and success on Saturday will see him lift a second FA Cup.
It will also help silence some of the criticism of the playing style adopted by Mourinho at Old Trafford as the club target a record-equalling 13th FA Cup success.
Conte to do some forward thinking
The biggest selection dilemma facing Conte heading into the final is his decision as to who will start in attack for the Blues.
Alvaro Morata managed just 11 Premier League goals following his big-money move from Real Madrid and has struggled to make an impact when called upon.
Meanwhile, Olivier Giroud joined from Arsenal in the January window and has become an instant cult hero at Stamford Bridge and would be a popular choice to start at Wembley.
Jose could be out of Luk
While Conte has a decision to make over his preferred striker, counterpart Mourinho is sweating over the fitness of his leading man.
Romelu Lukaku has hit 27 goals in his first season at Old Trafford and scored in every round of the FA Cup until the semi-final win over Tottenham.
The former Chelsea forward is struggling with an ankle injury suffered in the recent win over Arsenal and Mourinho has already hinted the 25-year-old may only be fit enough for the bench.
Emotional afternoon for all involved
There are likely to be tributes aplenty to Ray Wilkins on Saturday following the former Chelsea and United midfielder’s death last month.
Wilkins was a much-loved figure within the game and represented both clubs during a stellar playing career before working on the backroom staff at Chelsea for some time.
United will be keen to lift the trophy as a mark of respect to former boss Sir Alex Ferguson, who is still recuperating after surgery on a brain haemorrhage a fortnight ago – while Chelsea will also want to toast former captain Roy Bentley, who died in April aged 93.
