Celtic are interested in signing the Huddersfield defender Tommy Smith this summer.
According to Daily Record, the 27-year-old centre back is valued at around £4m but Celtic hope to sign him for £3m.
It will be interesting to see if they can secure an agreement with the Terriers. The Scottish giants are currently locked in talks for the defender.
Celtic need to improve their back four heading into the next season and Smith would be ideal. Neil Lennon has lost the likes of Boyata, Lustig and Benkovic this summer.
They have signed Jullien and Smith will be another quality addition.
