Marco Giampaolo is on the brink at Siena.

Siena sports chief Manuel Gerolin was forced to placate protesting fans at the team's hotel on Sunday after their defeat to Juventus.

Giampaolo insists he won't resign, but Tuscan sources say he is one defeat away from the sack.

Siena face Bologna this week, which will decide the immediate future of Giampaolo.
