The former West Ham striker has been under fire recently following alleged racial comments made to a former player and returned to Italy to escape the attention.
But he re-emerged from his self-enforced silence last week when he agreed a new two-year deal with the Robins.
"Sometimes you have to handle the situation and you have to accept and wait for the right time to say things and to say words," he told the Swindon Advertiser.
"If you know me, you'd know I would go out (and speak) every single morning that I read this news. But, with respect for the club and the situation, I probably became more mature as a person and as a manager.
"I have to protect my dignity, my job so it's obvious that from now I can talk about the future but there will be a time when I answer to people who say stupid things, even some fans, in the last few weeks."
