In one of the biggest January deals of all time, the Serbian has completed a £63m move to the Turin giants, sparking an angry reaction from Fiorentina supporters.
Vlahovic, who was strongly linked with a move to Arsenal earlier this month, has scored 20 goals across 24 club appearances this season and is emerging as one of the most prolific strikers in the European game.
The Serbian international has signed a four-year-deal with the Old Lady, who released a lengthy statement when announcing the deal.
“It would be reductive to describe Dušan as simply a force of nature,” read part of it.
“In addition to his physical prowess, he displays outstanding technique, power, class, and all-importantly, a clinical coldness in front of goal.
“With 44 goals, Dušan is also one of only two footballers born from 2000 on, alongside Erling Haaland, to have scored at least 40 goals in Europe’s top-5 leagues.
“A penalty box predator, 93% of his goals in Serie A, 41 out of 44, were scored from inside the penalty area, and already this campaign, he is the player who has attempted most shots, 75.
“These are numbers of this lethal striker. These are numbers to be updated together, game after game.”
