Serse Cosmi has been named coach of Siena.
Cosmi has penned a two-year deal.
He replaces Giuseppe Sannino, who has moved to Palermo.
"This is a wonderful day for me and finally I have the chance to start working from the beginning of a season," he told the official club website.
"That was my prerogative for 18 years of my career, then I stepped in for a few other Coaches and it certainly isn't the ideal situation.
"I can say I'm happy with this choice and thank President Massimo Mezzaroma and director Stefano Antonelli. They believed in me and I hope to repay them for that faith."
