Southampton assistant manager Danny Rohl has left St Mary's.
The Daily Echo says Rohl has left the club this summer and has returned to Germany.
The reasons behind Rohl's departure remain somewhat of a mystery but Hasenhuttl is believed to be untroubled by the development.
Hasenhuttl will not be looking for a replacement with the manager prepared to be front and centre on his own with his new look coaching line-up providing all the support he feels he needs.
Hasenhuttl and Rohl had been close before working together at Saints with the duo having previously helped guide RB Leipzig to a second place finish in the Bundesliga.
