Franciscus “Frank” de Boer
De Boer began his career as a left back at Ajax before switching to centre back, a position he made his own for many years in the national team. He won both the UEFA Cup and Champions League while at Ajax. However, after signing a 6-year contract extension with Ajax for the 1998–99 season, he and his twin brother Ronald took successful legal action to have it voided. Ajax had agreed orally that if a lucrative offer for one brother came by, he would be released provided the other stayed. However Ajax apparently backed down on that agreement after floating the club on the stock market and pledging to shareholders that it would hold both of the de Boers and build around them a team to recapture the UEFA Champions League
Both de Boers then joined FC Barcelona for 22 million pounds. However, they were unable to repeat his earlier triumphs and Frank suffered the ignominy of testing positive for the banned substance nandrolone. De Boer was suspended but he was reinstated after a successful appeal.
He briefly moved to Galatasaray in the summer of 2003 before joining Rangers in January 2004. He left Rangers in 2004 after Euro 2004 along with twin brother Ronald (his teammate at Ajax, Barcelona and Rangers) to play the rest of his football career in Qatar with Al-Rayyan.
De Boer announced his retirement from football in April 2006.
Having represented his national team 112 times,he was the most capped player in the history of the Netherlands national team, until Edwin van der Sar surpassed him. de Boer made his debut for the Netherlands in September 1990 against Italy.
De Boer also played for the Netherlands in the 1994 and 1998 World Cups, Euro 92, Euro 2000 and Euro 2004, but missed Euro 96 through injury. He is well-remembered for the arching 60-yard pass which allowed Dennis Bergkamp to score the last-minute goal that knocked out Argentina in the quarter-finals of the 1998 World Cup. During Euro 2000, hosted in his home country and Belgium, de Boer reached another semi-final with the Dutch team. de Boer missed an important penalty kick in the penalty shootout in the semi-finals, which led to defeat against Italy. He also missed a penalty during the match.
He ended his international career after an injury forced him to be replaced in a quarter-final game with Sweden at Euro 2004. The injury ruled him out from the semi-final match against Portugal, which the Netherlands lost 1–2.
