2009–10 Crystal Palace F.C. season

The Crystal Palace F.C. season 2010-11 was Crystal Palace's sixth consecutive season in the Championship.
 The previous season had seen Palace finish one place above the relegation zone, having been deducted ten points for going into administration.
 The CPFC 2010 consortium completed a takeover of the club in the close season and installed former Scotland manager George Burley as the club's new boss, with club legend Dougie Freedman continuing his role as assistant manager.
 However, after a poor start to the season, Burley was sacked on New Year's Day and Freedman named manager the following week.
 Under Freedman fortunes improved, and the club secured another season at Championship level shortly before the conclusion of the campaign.
During the 2005–06 English football season, Crystal Palace F.C. competed in the Football League Championship, following relegation from the FA Premier League the previous season.
Crystal Palace circuit is a former motor racing circuit in Crystal Palace Park in the Crystal Palace area of south London, England.
 The route of the track is still largely extant today but the roads are now mainly used for access to the Crystal Palace National Sports Centre located in the park, and to events within the upper parts of Crystal Palace Park.
 Some parts of the track are closed off but part is used for an annual Sprint Meeting held on the Spring Bank Holiday weekend, until 2017, when it was held on the August holiday weekend.
Crystal Palace F.C. was a short-lived amateur association football club who were formed in 1861 and became founder-members of the Football Association in 1863.
 Along with Wanderers F.C., Barnes F.C. and the N.N. Club, they were described by Charles W. Alcock as being the four clubs who formed "‘the backbone of the Association game’" in its early years.
 The club disbanded and disappeared from historical records around 1876.
The Crystal Palace Football Club Player of the Year is awarded at the end of each season.
 Since the inaugural award was made to John McCormick in 1972, 34 different players have won the award.
 Nine of these players have won the award for a second time, the most recent being Wilfried Zaha.
 Two players have received the award on more than two occasions, Jim Cannon won it three times and Julián Speroni won it four times.
 Paul Hinshelwood was the first to win the trophy in consecutive seasons, a feat since emulated by Andrew Johnson, Julián Speroni and Wilfried Zaha.
 Speroni is the only one to win it in three consecutive seasons.
 The current incumbent of the award is Wilfried Zaha, who was the 2016–17 recipient.
