Cologne are putting the final touches on a deal for Chelsea defender Tomas Kalas.
BILD says the Czech Republic international will move to Cologne on a season-long loan for next season.
Chelsea boss Jose Mourinho rates Kalas highly, having secured him to a new three-year deal last term, but feels he's not ready for a full Premier League campaign.
Instead, he is happy for Kalas to have 12 months away in Germany with Cologne, feeling it will be a step up from his previous spell in Holland at Vitesse Arnhem.
