Fiorentina president Andrea Della Valle says he was "totally stunned" by midfielder Riccardo Montolivo's decision to stall over a new contract.
The Italy international was expected to sign a new deal with the Viola but instead broke off talks in order to assess the options available to him.
Montolivo has been linked with Premier League clubs Arsenal and Manchester City, as well as Italian champions Inter, and Della Valle was shocked when the player refused to commit his future to the club at such a late stage.
"I was left totally stunned by this Montolivo contract renewal situation," Della Valle said. "There were only a few details left to be decided. I would hate for his agent to be involved in this turnaround."
Following Italy's 5-0 win over Faroe Islands on Tuesday night, the player sought to underline that he wants time to consider his options.
"My links with the fans and the city and not up for debate, but the contract extension is another question," he told Rai Sport. "We are talking about a decision that's relative to my future, so there is need of time to evaluate every aspect of it. My actual deal lasts until June 2012, so there is a long time to think about it."
