Celtic assistant manager John Collins has told the Daily Record that he was impressed with new signing Kristoffer Ajer during his trial at the club.
Ajer, 17, hit 13 goals in 47 games for Norwegian side IK Start, emerging as one of Europe's most highly-rated wonderkids as interest in his signature began to build.
Last month, Ajer joined Celtic on trial as he looked to impress his fellow Norwegian Ronny Deila, and he clearly did enough to tempt the Bhoys into a deal.
Celtic confirmed earlier this week that midfielder Ajer has signed a four-year deal with the Bhoys, and will join the club at the end of the season.
It's quite the coup for Celtic considering Ajer's burgeoning reputation, and fans will no doubt be keen to see what the 6ft 5in teenager can offer in the heart of midfield.
Now, Celtic's assistant manager John Collins has offered some insight into what he saw from Ajer during his trial in Glasgow, as quoted by the Daily Record.
Collins claims that he was impressed with what Ajer showed on trial, and pointed out that he showed composure in possession - but he must prove that he is worthy of a first-team place even after impressing so much on trial back in January.
"Young Kristofffer did very well last month," said Collins. "[He] 17-years-old, he fitted in very well on the training pitch and showed lots of composure, calm on the ball - a good football player. He will have to come in and prove himself like any player," he added.
