Aleksander Cerefin, a Slovenian lawyer and head of the country's football association, beat Dutchman Michael van Praag by 42 votes to 13 in UEFA's election held in Athens on Wednesday.
He assumes the presidency amid continued rumblings over a Champions League breakaway involving the continent's top clubs.
Aleksander Ceferin is probably someone to avoid picking a fight with -- whether that's verbally or physically.
The Slovenian is a 48-year-old lawyer who heads up one of the biggest legal firms in the Balkans, having replaced his father as company director in the family business.
for the UEFA presidency detailed that he specializes in criminal and commercial law, with a self-proclaimed "strong track record of defending human rights," while he has also applied his legal skills to the world of sport as well.
Secondly, he just happens to be a black belt in karate.
Now the father of three is entering a different arena after becoming the seventh elected president of UEFA, the richest continental federation in the world.
A former committee member of reigning Slovenian champion Olimpija Ljubljana, Ceferin took a significant step up the administrative ladder when becoming president of the country's football association (NZS) in 2011.
In 2015, he was re-elected on a second four-year term.
Under his control, Slovenia has slipped down FIFA's rankings -- from 26th in the year he took charge to 59th today -- but facilities have certainly improved.
In May, the NZS opened its new national football center -- replete with three pitches and a multipurpose sports training facility -- near the city of Kranj, 30 kilometers north of the capital Ljubljana.
