Chelsea defender Tomas Kalas is poised to complete a season-long loan move to newly-promoted Bundesliga outfit Cologne, according to reports in Germany. The 21-year-old made four senior appearances for the Blues towards the end of the 2013/14 campaign and made a positive impression, but Jose Mourinho looks set to loan out the young centre-back in order to gain some regular first-team experience.
German newspaper Bild say Chelsea hope the loan move will enable the Czech Republic international to return to Stamford Bridge in time to challenge John Terry or Gary Cahill for a first-team place at the start of the 2015/16 season.
Kalas spent two years on loan with Vitesse in the Eredivisie between 2011 and 2013, but the Bundesliga would represent a significant step up in class for the youngster, who made his Premier League debut in April's memorable 2-0 away win at Liverpool.
Cologne were promoted back to the Bundesliga after finishing champions in the second tier, but will be looking for reinforcements ahead of what promises to be a difficult campaign in the German top flight.
Chelsea, meanwhile, will stick with the centre-back pairing of Terry and Cahill, while 19-year-old Kurt Zouma will provide back-up in his first season at Stamford Bridge following his £12 million move from Saint-Etienne. Mourinho is also believed to be considering a move for Real Madrid centre-back Raphael Varane after agreeing to sell David Luiz to Paris Saint-Germain for around £48 million.
