The 16-year-old has had two trials at Arsenal, but is now set to join the Premier League side in a permanent move for an undisclosed fee.
“I can confirm that the transfer is close to being sealed. I won’t comment on any sums, but of course we are happy with the deal,” IFK Norrkopings sporting director Tony Martinsson told Fotbolldirekt.se.
“We are pleased, but of course we would have preferred to have seen Kristoffer stay in Norrkoping and evolve to a first-team player.
“He wanted to take this chance and we will not stand in the way.”
