With third place locked up, Feyenoord had nothing to play for anymore, which gives Van Persie's team access to the UEFA Champions League qualifiers. The Premier League icon gave Bulgarian stopper Plamen Andreev his first minutes of this season ahead of Timon Wellenreuther, who wasn't fit enough to start in the last game of the season.
The game against Heerenveen, who were still fighting to clinch a spot in the Eredivisie play-offs for UEFA Conference League football, started off badly for Feyenoord as Bulgarian centre-half Hristiyan Petrov headed the home side in front after four minutes.
A nasty collision between Petrov and his goalkeeper, former Dutch World Cup stopper Andries Noppert, forced the latter to get taken off after sixteen minutes.
19-year-old Serbian Milos Lukovic, who earned his second-straight start alongside 18-year-old talent Eser Gurbuz in Heerenveen's front three, doubled the home side's lead from the penalty spot after a foul from Gernot Trauner withheld the Serbian youngster from scoring.
Feyenoord grew increasingly unable to make a real impact in the first half and entered the break with a 2-0 deficit after Ayase Ueda failed to score thanks to a stellar save from Mickey van der Hart.
Feyenoord opened the second half with a more hopeful approach and saw former Brighton midfielder Jakub Moder nearly score, but the Pole's header just missed the post.
Lukovic later failed to beat Andreev before Feyenoord captain David Hancko saw his header narrowly miss the Heerenveen goal during injury time.
Heerenveen beat former boss Robin van Persie's Feyenoord and officially clinched a spot in the Eredivisie play-offs by finishing ninth with 43 points. Feyenoord end their season with 68 points and a third spot.
