Lecce insist Roma will be able to sign outright Mirko Vucinic at the end of the season.
The Serie B club's chief executive, Claudio Fenucci, said: "Mirko has signed for Roma, but Lecce holds 50 per cent of his registration. It's an open partnership. We feel we have an excellent partnership with the capital club, there is no problem, I think at the end of the season there will be an agreement between the parties.
"We have taken no agreement on the cost of the transfer."
