Jan Koller (born March 30, 1973 in Smetanova Lhota, Czech Republic, then Czechoslovakia) is a Czech football player, who currently stars as a striker for the Czech Republic national team and the Bundesliga club 1. FC Nuremberg in Germany. He is the all-time leading goal scorer for either the Czech Republic or the former Czechoslovakia, with 50 goals in 80 caps as of September 13, 2007.
Koller has an impressive physical presence (height: 2.02 m, nearly 6’8″ and weight 100 kg, about 220 pounds). Borussia Dortmund’s physio refused to comment on this phenomenon. Koller started his football training as a goalkeeper, but was converted to striker by the time he started his professional career. His training as a keeper saw some use in the 2002-03 season. In one Bundesliga match at Bayern Munich, Borussia Dortmund’s keeper Jens Lehmann was sent off about midway through the second half, and Koller moved from striker to keeper after he had already scored once in the first half. He kept a clean sheet for the rest of the match against good opportunities by Michael Ballack and others, and was named the Bundesliga’s top keeper of the week for his performance. Nevertheless Dortmund lost this important match. Wikipedia
