[[File:Feyenoord logo 100 years.svg|thumb|Logo for the club's 100th birthday]]
In the [[2008–09 Eredivisie|2008–09 season]], Feyenoord celebrated their 100th birthday and organised many events throughout the year. The old "golden logo" returned as Feyenoord's official logo, which had earlier been presented at the 2007 New Year's brunch.<ref>[http://www.feyenoordleven.nl/feyenoord100jaar.html Feyenoord 100 jaar] {{webarchive |url=https://web.archive.org/web/20070927225155/http://www.feyenoordleven.nl/feyenoord100jaar.html |date=27 September 2007}}, feyenoordleven.nl</ref> During the summer, a historical tournament was held between Feyenoord and the three opponents they met in the European Cup finals – Borussia Dortmund, Tottenham Hotspur and Celtic – named the [[Feyenoord Jubilee Tournament]].<ref name="feyenoord100">[http://www.ad.nl/sport/article1004946.ece Borussia, Spurs en Celtic naar Kuip], ad.nl</ref>

Midway through the season, manager Verbeek was sacked due to disappointing league results. His assistant, Leon Vlemmings, took over as manager. The results in this period improved slightly, resulting in securing a spot in the playoffs for the final Dutch Europa League slot.

For the [[2009–10 Feyenoord season|2009–10 season]], Feyenoord appointed former assistant manager and Feyenoord footballer [[Mario Been]] to take over from Vlemmings. Been, after achieving minor European successes with NEC, was considered the ideal candidate for the job. Former manager Leo Beenhakker, at the time manager of the [[Poland national football team|Poland national team]], took over as technical director. Partly because of this position, Beenhakker was able to attract more investors to the club, leading to some unexpected signings, including [[Sekou Cissé]], [[Dani Fernández (footballer, born 1983)|Dani Fernández]] and [[Stefan Babović]].

On 24 October 2010, Feyenoord lost heavily to PSV 10–0. In mid-January 2011, Beenhakker resigned after multiple clashes with the Feyenoord directors.<ref>[http://www.ad.nl/ad/nl/5619/Feyenoord/article/detail/1892970/2011/01/17/Leo-Beenhakker-stapt-zelf-op-bij-Feyenoord.dhtml Beenhakker stapt op], AD.nl</ref> His replacement was former Feyenoord player [[Martin van Geel]], who at the time was working as technical director for fellow Eredivisie club Roda JC.<ref>[http://www.nieuwslog.nl/2011/02/24/martin-van-geel-nieuwe-technisch-directeur-feyenoord/ van Geel nieuwe technisch directeur] {{webarchive |url=https://archive.today/20120906032607/http://www.nieuwslog.nl/2011/02/24/martin-van-geel-nieuwe-technisch-directeur-feyenoord/ |date=6 September 2012}}, nieuwslog.nl</ref>

In July 2011, a majority of players in the squad voted to oust Been as club manager; 13 of 18 players voted they had lost all confidence in Been's ability to successfully manage the club.<ref>[http://feyenoordreport.nl/2011/07/14/dit-zijn-de-feyenoorders-die-mario-been-hebben-weggestemd/ Feyenoorders die hebben gestemd] {{webarchive |url=https://web.archive.org/web/20120425231521/http://feyenoordreport.nl/2011/07/14/dit-zijn-de-feyenoorders-die-mario-been-hebben-weggestemd/ |date=25 April 2012}}, feyenoordreport.nl</ref> Been's subsequent sacking became global news, if only because reports of Been's firing quickly became a trending topic on Twitter, leaving people around the world to wonder who exactly Been was.<ref>[http://nos.nl/artikel/255919-vertrek-mario-been-wereldnieuws.html Vertrekt Been wereldnieuws], NOS.nl</ref>

After Louis van Gaal turned down an offer to manage Feyenoord, the club approached former Barcelona defender [[Ronald Koeman]], who had played for Feyenoord during the late 1990s. With his eventual hiring as manager, Koeman became the first to ever serve as both player and head coach at all teams of the so-called "[[Big Three (Netherlands)|traditional big three]]" of Dutch football: Ajax, PSV and Feyenoord. Moreover, he played and managed these teams in the same order.<ref>[http://www.nu.nl/sport/2570054/ronald-koeman-nieuwe-trainer-feyenoord.html Koemand nieuwe trainer Feyenoord], nu.nl</ref>
