The Rossoblu midfielder has rubbished speculation surrounding his future as nothing more than "inventions"
The 30-year-old attacking midfielder, who has scored 16 times in 68 appearances for Felsinei since joining in 2011, has reportedly been the subject of interest from both the Bianconeri and AC Milan.
However, the former Livorno playmaker has moved to distance himself from those stories and looks to have dashed the hopes of his suitors.
"I read so many inventions on my behalf," he revealed in Corriere di Bologna.
"I'm the leader and the captain of Bologna."
The news will no doubt delight Bologna fans, with Diamanti becoming a crowd favourite ever since his move from Brescia.
Earlier this month, Rossoblu president Albano Guaraldi had given the Bianconeri a final deadline in their chase for the player, but with that date of July 15 having long since passed, it appears the player is now firmly off the market.
His current deal runs until June 2017.
