Background: Sir Walter Winterbottom, CBE (31 March 1913 - 16 February 2002) was the first manager of the England football team (1946-1962) and FA Director of Coaching. He resigned from the FA in 1962 to become General Secretary of the Central Council of Physical Recreation (CCPR) and was appointed as the first Director of the Sports Council in 1965. He was knighted for his services to sport in 1978 when he retired. The Football Association marked the 100th anniversary of Winterbottom's birth by commissioning a bust which was unveiled by Roy Hodgson at St Georges Park on 23 April 2013 in recognition of his outstanding contribution to the development of English football.
Context: Walter Winterbottom has the distinction of being England's first, youngest and longest serving England team manager; he is also the only England manager to have had no previous professional managerial experience. In all matches in which he was in charge, England played 139, won 78, drew 33, and lost 28; goals for 383, against 196. At home England lost six matches in sixteen years. England won the British championship in thirteen out of his sixteen seasons (seven times outright and six times sharing top place). In the World Cup tournament England qualified on all four occasions, reaching the quarter finals twice, playing 28 matches, winning 15, drawing 7 and losing 6; goals for 75 against 35 (including World Cup qualifying matches).  Although he had coaching and managerial responsibilities, Winterbottom never had the power to pick his own team (it was chosen by a selection committee). Over time his technical knowledge increasingly influenced selectors. Finally, prior to Alf Ramsey's arrival in 1962, he convinced the FA that the team manager must have sole control of selection. During his time Winterbottom repeatedly warned the English football establishment that countries in Continental Europe and South America were overtaking England and that English football had to change. His sixteen years as England team manager helped greatly in creating a modern and competitive national team and four years after his departure in 1966 England won the World Cup. His innovations included the introduction of England B, Under 23, youth and schoolboy teams providing players with continuity and experience in international football before being selected for the full England team.  Notable victories during his era were 10-0 away to Portugal in 1947, 4-0 away to Italy in 1948, 4-2 at home to Brazil in 1956 and 9-3 at home to Scotland in 1961. Notable defeats were losing 1-0 to the USA in the 1950 World Cup and 6-3 at home to Hungary in 1953 when England lost her unbeaten home record to a foreign team, followed by a 7-1 away defeat to the same team in 1954.
