The former national team captain and center back has negotiated for a while with St Louis City, but now the parties have agreed.
The only thing left for the transfer to be completely clear is for Mellberg to receive the necessary permits to work in the USA.
"I can't wait to build on the foundation that has already been laid here and the massive support from the fans that gives this team the energy to be successful", he says.
Current as national team captain
Mellberg has trained Brommapojkarna together with Andreas Engelmark for the past two years. Before that, he was active in Helsingborg. He started his coaching career in BP in 2016-2017.
Last winter, he was a candidate for the national team coach, as Janne Andersson's successor, a task that later went to Jon Dahl Tomasson.
Diego Gigliani, CEO of St Louis City, comments on the recruitment of Mellberg:
"After careful consideration, we are pleased to welcome Olof as our new head coach and are convinced that he will fit well with St Louis City."
Gets results
"During his four years as head coach for Brommapojkarna, he has shown a consistent ability to exceed expectations and get results. Moreover, his passion for developing young players, strong reputation on the market, and previous playing experience at elite level in the sport were all additional reasons why we were convinced that he was right for the role."
Olof Mellberg belonged to clubs such as Degerfors, AIK, Racing Santander, Aston Villa, Juventus, Olympiakos, Villarreal, and FC Copenhagen during his active playing career. He played 117 national team matches.
In St Louis City, Swedes Rasmus Alm and Joakim Nilsson play.
