Fifa has blocked defender Christian Chivu's £12.5m move to Roma.
The Romania international's move was denied because the Italian Serie A club owes transfer money to another club.
Roma has not yet paid Peruvian club Sporting Cristal for the purchase of Gustavo Vassallo Ferrari.
Fifa has not disclosed the debt, but says it will lift the transfer freeze when the debt has been cleared.
Chivu was introduced to Roma fans on Wednesday after signing a five-year deal. |
