The Swedish-born tactican joined Bucs on a three-year deal earlier this week, and he was unveiled by club's chairman Dr Irvin Khoza on Monday.
He will be eager to hit the ground running as the Buccaneers desperately need to move up the log table following a run of nine games without a win.
The Soweto giants are currently placed 10th on the log after 18 league matches.
Pirates had been without a permanent coach since Muhsin Ertugral resigned at the beginning of November 2016 following a 6-1 defeat to SuperSport United.
Augusto Palacios was hired on an interim basis soon afterwards, but the Peruvian coach found the going tough as positive results were not forthcoming.
