Jan Koller is one of the tallest players in the game and uses his height to great effect for club and country.
Club: Borussia Dortmund
Debut: 09/02/99 v Belgium
At 6ft 7in, he acts as a target man up front but also possesses deceptive pace and a neat touch for such a big player.
Koller came to prominence in Belgium with Lokeren and Anderlecht, where he was named Player of the Year in 2000.
He scored 14 goals in his first 14 internationals and his six in the Euro 2004 qualifying campaign took him past Pavel Kuka's national record.
He was a major factor in the Czech Republic's recent 20-match unbeaten run and will be vital again in Portugal.
Now with Borussia Dortmund, Koller won the Bundesliga title in his first season in Germany in 2002 and has been an almost ever-present in the side.
Did you know? Koller started his career as a goalkeeper before his pace earned him a striking role.
