Celtic fans were full of praise for Kristoffer Ajer after a great performance against Hearts.
Playing at full-back, the defender was vital as Celtic ran out 3-1 winners in the league, with Ajer causing the Hearts players all sorts of problems throughout the 90 minutes.
Many Celtic fans were full of praise for Ajer on Twitter, with many calling him the star man in the victory for Neil Lennon’s men.

Read Celtic’s verdict
If you don’t think Ajer is one of Celtic’s best future prospects, then…
He played out of position today and played a blinder yet again, which just shows how good he really is.
Looking to the future, he could be another Celtic great if he sticks at it, and could be vital if Celtic are to eventually secure ten in a row.
