After passing through different youth levels at KK FMP Zeleznik, Milan Mačvan started his senior career in that same club at the beginning of the 2007/2008 season, without a contract being underage, under the head coach Vlada Vukoicic. He appeared in five games of the Adriatic League and made his debut in a game of the EuroCup (performing 4 points and 1 rebound), than when he turned 18 on November 16th, he finally signed his first professional contract and decided to move to KK Hemofarm Vrsac, that payed a buyout of € 150,000 for him.
So Milan joined back the head coach Miroslav Nikolic, who coached him in the Under 19 Serbian National Team that had won the Gold Medal at the Under 19 World Championship 2007 that summer. Few months later, the club brought in also coach Vukoicic, in a sliding door process where Milan stood as the pivotal player, destined to become the team leader.
It happened already in the 2008/2009 season, when Mačvan scored in double figures both in the Adriatic League (10.9 points, more 4.4 rebounds for 12.1 of efficiency) as well as in the EuroCup, where he performed 11.3 points and 4.2 rebounds per game, conquesting the honor to be awarded as the EuroCup Rising Star 2009, receiving the trophy from the President & CEO of Euroleague Basketball, Jordi Bertomeu.
Previously during the season, at the 2009 Nike Hoop Summit game held on April 11th at Portland's Rose Garden, Milan Mačvan was the MVP, performing a sensational game in which he wrote a "double-double" as the top scorer with 23 points and the top rebounder with 14 balls grabbed under the boards, and he also added 6 assists, showing the modernity of his game and leading the International team to get the first win since 1998...
He improved his game even more in the following season 2009/2010, as showed by the 14.6 points, 5.8 rebounds and 18.2 of efficiency in the Adriatic League, but also from the attention that every coach of the EuroCup dedicated to him (9.5 points, 3.6 rebounds). No matters, Mačvan was ready to be the most important player of the 2009/2010 season in the Adriatic League and in the EuroCup, and he started the season flying higher than ever.
He was simply unstoppable on court, performing 19.2 points more 6.7 rebounds and 26.1 of efficiency in the Adriatic League, as well as 17.0 points more 8.0 rebounds in the EuroCup, after roaring in the Euroleague Qualifying Round with 20.8 points and 4.5 rebounds.
On December 17th, 2010, when the legendary club of Israel, Maccabi Tel Aviv, announced to have signed Milan Mačvan with a five-year contract, everyone was ready to say that he was clearly the best power-forward of Europe. And it was indisputably the truth.
