Czech international defender Tomas Kalas has ended his nine-year stint as a Chelsea player by completing a permanent transfer to Sky Bet Championship club Bristol City according to The Blues’ official website.

The 26-year-old Olomouc-born centre-back joins The Robins on a permanent basis following a successful loan spell at Ashton Gate last season.

Kalas made 41 appearances for Bristol City as they fell just four points short of the play-off places following a solid campaign.

It has been reported that Kalas has now completed a permanent move to Bristol City with The Robins paying a club-record transfer fee for the defender, the value of which has remained undisclosed. The player has signed a four-year deal at Ashton Gate.

Despite joining Chelsea in 2010, Kalas has made just four first team appearances for The Blues and he has been loaned out to no less than five different clubs. The defender has featured for Dutch club Vitesse Arnhem, German club FC Koln and English sides Middlesbrough, Fulham and Bristol City.

Kalas has a promotion from the Sky Bet Championship on his CV already from his time with Middlesbrough and the Czech international will be eyeing a repeat of that feat with latest club Bristol City.
