On 26 June 2017, De Boer was announced as the new manager of Premier League side Crystal Palace , replacing the recently resigned Sam Allardyce . He signed a three-year deal with the South London club,   but was sacked 10 weeks later when Palace lost their first four league matches of the season without scoring a single goal – the first team in 93 years to have begun a top-flight season in such a fashion.  He left having managed the team for only 450 minutes of game time of a Premier League team, making it the shortest reign of the Premier League era (in terms of number of matches, rather than number of days).  De Boer's only win came in an EFL Cup second-round game, in which Crystal Palace won 2–1 against Ipswich Town .   He was replaced by Roy Hodgson . 
Since 2010, Davids had been living in North London with his partner and had been participating in street football as well as managing Sunday league amateur side Brixton United.  On 11 October 2012, Davids joined League Two side Barnet in a player-manager role, alongside Mark Robson . The next day, on his managerial debut for Barnet, his side lost 4–1 at Underhill to Plymouth Argyle which Davids had left himself out of the squad for this League Two game.  They followed this up with a 4–0 home win over Northampton Town where Davids played the full match, captaining the team and being voted Man of the Match.  In November, he started against Morecambe which Barnet lost 4–1. Near the end of December 2012, following the departure of Robson, Davids took charge of the club by himself.  Davids scored his first goal for Barnet in February 2013 in a 2–0 home victory over Southend United . 
The World Cup finals remain football’s premier tournament, but other important tournaments have emerged under FIFA guidance. Two different tournaments for young players began in 1977 and 1985, and these became, respectively, the World Youth Championship (for those 20 years old and younger) and the Under-17 World Championship. Futsal, the world indoor five-a-side championship, started in 1989. Two years later the first Women’s World Cup was played in China . In 1992 FIFA opened the Olympic football tournament to players aged under 23 years, and four years later the first women’s Olympic football tournament was held. The World Club Championship debuted in Brazil in 2000. The Under-19 Women ’s World Championship was inaugurated in 2002.
