Both Celtic and Swansea City have held talks with Michael Kollner over their respective managerial vacancy positions.
According to Wales Online, cited by HITC, both sides have had discussions with the former FC Nurnburg boss, despite the German having limited first-team managerial experience.
The 49-year-old is highly thought of in his native country and led his former side back to the Bundesliga last year.
Kollner was then relieved of his Nurnburg duties back in February after a poor run of form.
The Hoops remain on the hunt for a permanent boss after Brendan Rodgers left the club for Leicester City back in February.
Former Celtic manager and midfielder Neil Lennon has been in interim charge of the club since then and has guided the club to an eighth Scottish Premiership title.
Lennon has also led Celtic to the Scottish Cup final against Hearts, with the Scottish giants aiming for a domestic ‘treble treble’ at Hampden Park this weekend.
Who do the bookies see as the next permanent Celtic boss?
Moyes is currently the surprise favourite with the bookies to land the Celtic job.
Newcastle manager Benitez is second in the list with the bookmakers despite ongoing talks with his current side.
Interim boss Lennon is third in the list of favourites despite possibly clinging a ‘treble treble’ this weekend.
German Kollner has emerged on the list after the recent reports and is the fourth favourite.
Former Chelsea boss Villas-Boas has been in and around the list of potential managers and remains in the top five with the bookies.
