LONDON — Chelsea says defender Tomas Kalas will join German side Cologne on a season loan from July 1.
The 21-year-old Kalas made his Chelsea debut in the 2-0 win against Liverpool at Anfield in April and started in the last game of the season, a 2-1 victory over Cardiff. He also has made one appearance for the Czech Republic.
Last season, Cologne won promotion back to the Bundesliga after winning the second tier of German football by six points.
