U.S. men's national team defender Mark McKenzie has completed his much-anticipated move to KRC Genk, Philadelphia Union announced on Thursday.
McKenzie will join the Belgian side for what the club called a "multi-million dollar fee", with the Philadelphia Inquirer reporting that fee as around $6 million (£4.4m).
However, it could rise with performance bonuses and Union will also have a sell-on fee, much like the one they have with Brenden Aaronson who was sold to RB Salzburg recently.

McKenzie's move to Genk comes amid plenty of European interest, with Celtic being among the more active in their pursuit of the young American.
