Celtic are keeping tabs on Chelsea defender Tomáš Kalas ahead of a potential January move.

The 25-year old centre-back is currently on loan with Bristol City, and has made ten appearances for the Robins since joining on a season-long deal in the summer.

However Celtic are reportedly interested in breaking that loan deal ahead of potentially bringing the Czech Republic international to Celtic Park in January, with manager Brendan Rodgers keen to strengthen at the back.

Chelsea are thought to possess the option to recall Kalas in January, and reports suggest that he could be made available for a permanent move away from Stamford Bridge.

And according to ClubCall, as cited by the Bristol Post, the Hoops had scouts in attendance on Wedensday night, when Bristol beat Ipswich Town 3-2 at Portman road.

If Celtic do decide to firm up their interest, the Scottish champions will be expected to fork out a significant fee to land the former Fulham and Middlesbrough loanee, with Kalas’ contract still having three years remaining.
