CELTIC were given a scare when new signing Kristoffer Ajer was carried off with a knee injury at the start of the Norwegian season.
The beanpole 17-year-old midfielder, who agreed a £750,000 move from IK Start in the January transfer window, will arrive at the SPFL champions in the summer.
Former Norway manager Egil Olsen was impressed by the talented holding midfielder before he was forced to go off.
Olsen said: “Kristoffer’s injury is bad news for Start because he was their best player until then.
