Lazio coach Edy Reja hopes Aleksandar Kolarov's future will be decided soon.
The Serbia international has been linked with Manchester City in recent months, and reports over the weekend suggested a fee had been agreed after City executives travelled to Rome.
However, no deal has been reached between the two clubs so far for the 24-year-old.
"For over a month he has been linked with a move away from Lazio but nothing has happened," said Reja.
"I hope a decision will be taken soon.
"It's clear that if he leaves, I will need to find an alternative player for that position."
Kolarov is under contract with the Serie A club until June 2011 and has a buy-out clause of 22.5million euros.Reuse content
