(Reuters) - Chelsea centre back Tomas Kalas has signed a new four-year contract with the Premier League club and will spend next season on loan at Championship side Fulham, both clubs said on Thursday.

The 24-year-old Czech Republic international also spent last season on loan at Fulham, making 36 league appearances in England's second tier and helping the club reach the playoff semi-finals, where they lost to Reading.
