Mauricio Pochettino has reiterated his commitment to Saints.
He said: "I must also highlight that the structural changes behind the scenes here have not affected my position at the club.
"I spoke with Katharina Liebherr on the day after Nicola Cortese's departure and we were reassured that we have her full support towards our role with the team.
I remain committed to being manager of Southampton Football Club. It is a great responsibility, and one that I enjoy.
