Mark McKenzie is the second Union player to move to Europe in a matter of months, following Brenden Aaronson's move to RB Salzburg.
The Union have announced the United States men's national team and
has signed with Belgian sideGenk
McKenzie is headed to KRC Genk on a reported fee of approximately $6 million dollars as well as a sell-on fee plus performance add-ons.
McKenzie, who already has interest from Scottish Premier League Celtic FC, would fill needs along the backline for Genk.
I’ve been able to coach and watch Mark develop first hand since he joined the Union Academy, and his trajectory since then has been nothing short of impressive,”
said Union Head Coach Jim Curtin
“Mark has been a reliable and skilled center back, one of the best defenders in our league this year. His dedication to training, learning and drive to improve paired with his passion, moral grounding, and personality off the field, makes him an invaluable member of any team and locker room.
"He will most certainly be missed at the Union, but I am so proud of him and have no doubt Mark will excel with Genk."
The 21-year-old center back signed a homegrown deal with the Union ahead of the 2018 season and made 48 appearances. McKenzie is coming off his best professional season, helping lead Philadelphia to the Supporters' Shield and earning MLS Best XI honors.
