Tottenham are stepping up their efforts to capture Vlahovic from Fiorentina after making an appealing offer to the Italian club.
Spurs are keen to boost their attack force amid doubts about Kane's future, with Manchester City reportedly interested in signing the Englishman.
Nuno, on the other hand, is eager to play with two up front and wants to bring in one of Europe's top young attackers.
Vlahovic surprised Serie A last season with 21 goals, prompting a number of clubs to express interest in the Serbia international.
Arsenal, Atletico Madrid, and Inter Milan have all been connected with the 21-year-old.
According to Viola News, through Sport Witness, Tottenham are willing to pay the forward €5 million each year after taxes and bonuses for the next five years, including a €2 million signing bonus.
