The Italian has admitted he can understand the winger's desire for first-team soccer and has revealed the England international could be transferred before the end of August.
Manchester City boss Roberto Mancini has revealed that Adam Johnson could be on his way out of the club this summer.
The winger, who was a member of England's starting lineup against Italy in midweek, did not feature in the match-day squad as City began its title defense with a 3-2 victory over Premier League newcomer Southampton on Sunday.
Speaking after the game, the 47-year-old admitted that Johnson may have to look elsewhere in order to get the first-team soccer he desires.
"Adam wants to go to play. We are waiting for the next ten days to find a solution for him," he told reporters. "If we find a good solution Adam can go to play. I think this is better because he is young, he's a good guy and he deserves to play always and here it is not possible.
"We'll wait 10 days. If after 10 days we don’t find a solution for him he’ll stay here. He's happy and maybe he can have more chances."
The Italian did go on to concede, however, that he would be sorry to see the 25-year-old depart the club but understands the former Middlesbrough man's desire for regular match action.
He added: "He can have a future here but you have to understand when you are 25-years-old you want to play always.
“If he decides he wants to play always I agree with him and if he wants to leave I am sorry because I think he is a good guy and is different player from the other striker and wingers but I understand he wants to play."
