The Mezzaroma family insist coach Alberto Malesani has the full backing of Siena's new owners.
Malesani was said to be under pressure to keep his job this week.
But in a statement last night, the club's owners said: "Starting from the question of coach Alberto Malesani, he has earned the trust of the club. We only considered it necessary to make a reflection on Sunday's defeat, as is only right for a team ranked last.
"I now urge everyone to have a minimum of patience."
