Tottenham can Sign Versatile Star for £18m-£22m

Tottenham must secure the signing of a natural center forward this winter as the strike-force is one department where they seriously lack quality and depth.
However, if reports are anything to go by then the North Londoners are also monitoring a Croatian midfielder in the form of Marcelo Brozovic of Inter Milan.
According to reports (Corriere dello Sport) in the Italian media, Spurs are one of the few clubs watching the 23-year-old Croat who joined the Nerazzurri from Dinamo Zagreb. He has taken little time in replacing compatriot Mateo Kovacic who left for Real Madrid in the summer.

As per the provided Corriere dello Sport link, only an offer of around £18m to £22m can convince Mancini to sell the versatile star. This season, in 12 appearances for the Serie A side, Brozovic has scored 3 goals and provided an assist.
Spurs already have more than a decent midfield department with quality players for first team and on the bench. Players like Dier, Dembele, Mason and Alli have impressed big time this season.
Hence, it will be fair to say that Mauricio Pochettino should only focus on securing an out and out striker in the upcoming January transfer window.
