The Thailand club confirmed Middendorp’s appointment on their official website.
“Bangkok United launch Ernst as the club’s technical director,” read the club statement (translated from Thai to English).
Middendorp parted ways with the Team of Choice a fortnight ago following a poor start to the season that saw the team collecting 10 points in 10 matches.
The German mentor was linked with a move back to Free State Stars, but the 58-year-old has decided to join Bangkok United as the technical director instead.
