Milan send offer for 18-year-old striker Kostic | OneFootball

La Gazzetta dello Sport reports that Milan are pushing to sign 18-year-old striker Andrej Kostic and have made an offer to sign him from Partizan Belgrade this month.

Milan are pushing to sign Partizan talent Kostic on a permanent deal and have now sent an offer of €4m-5m to secure his signature in the current transfer window.

Football Italia already reported Milan’s interest in Kostic at the end of December. The striker’s agent Darko Ristic, is also the representative of Juventus star Dusan Vlahovic, another Milan target in attack.

Kostic, however, would initially play in the Milan Futuro squad in Serie D before gradually joining the senior team coached by Massimiliano Allegri.

Vlahovic, on the other hand, is a Rossoneri target for the summer transfer window, given that the contract of the Juventus star expires at the end of the season.

Kostic is Partizan’s second-best goal-scorer this season with nine goals in 27 appearances across all competitions. The 18-year-old has only collected 791 minutes of football this season, so he’s averaged one goal every 88 minutes.
