Juventus are no longer interested in signing Lukaku after the strong rejection from the Juventus fans and also I think they now have an adequate front line and don't need Lukaku.
And indeed at this time there are very strong rumors that Jose Mourinho is interested in bringing in Lukaku after the Belgian national player is no longer used by Chlesea, but that is with a loan option.
I think if this offer is seriously made by the Roma team then it will most likely be realized after Chelsea really don't want Lukaku anymore.
the reason is also obviously different, the request for money was not compatible for the two teams, Juventus sold their striker and wanted Lukaku plus a tidy sum. Which Chelsea didnt like very much. It happens often unfortunately.
