The Italy international has been linked with a move away from the Granata throughout the summer but remains a Stadio Olimpico player for the time being.
“He is a player I want to keep, but he has to agree with me,” Cairo said ahead of Toro’s Europa League tie with Brommapojkarna. “We have spoken about it and we will speak again.
“If he wants to go we can’t keep hold of him. On the contrary, if he wants to stay and renew his contract I would be very happy to keep him.
“For me it is still 50-50.”
Cairo then commented on this evening’s third qualifying round second leg, with Toro 3-0 up from the first leg in Sweden.
“In the first leg we did very well, the important thing is to have a team that will play with the same concentration that they did in Sweden.”
