Tottenham will have to pay Italian Serie A side Fiorentina at least £60 million if they wish to sign Dusan Vlahovic in January.
The 21-year-old striker is a key target for both Aresenal and Tottenham, as they look to freshen up their respective forward lines.
Vlahovic is seen as one of the best young forwards in Europe, having scored 21 goals in all competitions last term.
He has eight in Serie A this term, and is being tracked by a host of top teams in Italy and the rest of Europe.
But Fiorentina will only sell him in January for a mega fee, according to La Nazione.
