The 17-year-old starlet is heading to Anfield after Rafa Benitez tied up the deal personally.
"'This is Rafa' he said," recalled sports director Per Rud to the club's official website when asked about how the transfer came about. "I almost thought it was a lie!
"We are pleased and proud that Nikola has gone to one of the world's best football clubs. We would have liked to have earned more money from Nikola but his injury and the fact that his contract expired in the New Year made it difficult.
"Liverpool acted extremely well in all cases and knew all the details. They have been fair in the process and could've waited until the New Year but they will have him over now."
