Kevin Keegan at Hamburg
After 323 games and exactly 100 goals for Liverpool, and lifting the club's first European Cup as his final act for the Reds, the 26 year-old Kevin Keegan joined Hamburger SV for a then German record fee of £500,000 in the summer of 1977.
Big things were expected of the new highest-paid player in West Germany and Keegan certainly delivered - in his three years he led the forward line as the club won their first Bundesliga title and reached a European Cup Final, with Keegan individually picking up consecutive Ballon d'Or awards (the only British player to ever do so) as Europe's best player in 1978 and 1979 and the nickname 'Mighty Mouse' from the Hamburg fans.
On the foundations that Keegan helped build Hamburg went on to dominate the Bundesliga in the five years after his departure in 1980, never finishing below second place in the league, and in 1983 they won the European Cup.
