The Sloveninan international will follow the same path as Goran from Red Star Belgrade to the Lane after agreeing to join us on Tuesday.
The 25-year-old will join us on a four-year deal once work permit formalities are concluded.
Milkenko and Goran spent three successful seasons together at Red Star Belgrade.
The midfielder revealed: "I knew a lot about the club before I came to England because Goran Bunjevcevic is my big friend and we talk a lot about the games, the players.
"I saw the game against Liverpool and this is a very good team, big players and a very big club.
"I talked with Goran every day. I talk a lot about the club, the players, Glenn Hoddle, England and Goran said everything about the city of London is very nice. I can now see that is true."
Milenko Acimovic is looking forward to linking up again with his great friend Goran Bunjevcevic at Spurs.
