Chelsea defender Tomas Kalas is set to return to the club in the New Year after failing to make an impression at Bundesliga side FC Koln, according to the Daily Star.
The centre-back is widely regarded as one of the Blues' best young players, but has endured a nightmare time in Germany and may now be shipped out to Harry Redknapp's Queens Park Rangers.
A sign of Kalas' future importance to the club was his selection during Chelsea's 2-0 victory over Liverpool at Anfield last season, with the Czech Republican nullifying the threat of Luis Suarez and Daniel Sturridge in a performance of class and solidarity.
The 21-year-old had previously been plying his trade on loan in the Eredivisie before that, and made 76 appearances in two seasons in the Netherlands as the club battled to compete in the Europa League.
Manager Jose Mourinho was delighted with his debut last term, though with the likes of Gary Cahill, John Terry and Kurt Zouma above him in the pecking order faces a huge battle to break through into the Blues' starting line-up.

A move to FC Koln was expected to see him continue to develop, but he is still yet to feature for the side after signing on loan in the summer and has spent the majority of his time in Germany languishing on the substitutes bench or amongst the reserves.
It has been a move that has backfired tremendously, and Redknapp could swoop with the former Tottenham and Portsmouth manager keen to improve his side's chances of remaining in England's top flight.
The R's have built some momentum in recent weeks with Charlie Austin particularly to the fore, but still need to splash the cash in order to prevent dropping down to the Championship.
