Career
Melchiorri started his career with Serie Doctorate amateurs Tolentino and successively joined Siena in January 2006. He made his Serie A debut on 20 December 2006 in a game against Empoli when he came on as a last-minute substitute for Cristian Molinaro. Melchiorri was sold to Sambenedettese in co-ownership deal in 2007.
He was then fully signed by Sambenedettese in 2009.
He was successively forced to quit football after being diagnosed with cavernoma and undergoing surgery as a result. He resumed active football later in 2010 with former club Tolentino (Eccellenza), scoring 30 goals in 54 matches.
In 2012-2013 Melchiorri was sold to Maceratese (Serie Doctorate) and he scored 22 goals in 30 matches. His impressive performances caught the attention of Serie B club Padova, who signed him in the summer of 2013.
He scored six goals in a rather unfortunate season for Padova, which ended with relegation and then the club being declared bankrupt.
He successively joined Pescara, another Serie B club, in the summer of 2014 on a free transfer.
