Alexander Blessin has been appointed coach of promoted Bundesliga club St Pauli Hamburg, according to German and Belgian news reports.
Dailies Hamburger Abendblatt and Het Nieuwsblad said that Blessin has signed a three-year contract at last season's German second division champions in a move from Belgium's Royal Union Saint-Gilloise.
There has been no official confirmation from the clubs so far.
Blessin, 51, would succeed Fabian Hürzeler who has joined Premier League club Brighton & Hove Albion.
His Saint-Galloise contract is until 2025, and the reports said that St Pauli will have to pay a takeover fee of less than €1 million ($1.07 million).
Blessin is little known in Germany. He played seven Bundesliga matches for VfB Stuttgart and as a coach was in charge of RB Leipzig's under-17 and under-19 teams before going abroad to Belgium's Oostende and Italy's Genoa.
He came to Saint-Gilloise last year and led them to a first Belgian Cup title in more than a century and second in the league in the past season.
St Pauli meanwhile announced they had signed Scottish attacker Scott Banks on a permanent basis.
The 22-year-old had previously been on loan from English Premier League club Crystal Palace.
Banks arrived at St Pauli at the beginning of last season but made only four brief appearances due to a cruciate ligament rupture, scoring once.
