Chelsea defender Tomas Kalas is interesting Celtic.

The Birmingham Mail says Bristol City loanee Kalas is wanted by Celtic.

Kalas, 25, is playing for the promotion chasing Robins this season - this is now his seventh loan spell away from parent club Chelsea.

Celtic, who have named Neil Lennon as interim boss while they search for a permanent successor to the departed Brendan Rodgers, are eight points clear of second placed Rangers.

Kalas' contract at Stamford Bridge runs for another two years beyond the end of this season.
