Sergej Milinkovic-Savic is ready to quit Lazio.
Corriere dello Sport says the midfielder has been in regular contact with Lazio president Claudio Lotito since the end of last season.
And Milinkovic-Savic, 24, has told Lotito he wants to leave this summer.
Lazio and representatives of Milinkovic-Savic are in contact with Manchester United, which are preparing an offer for the midfielder.
Juventus are also keen - and will firm up their interest should Sami Khedira choose to leave.
Lotito is demanding 100m to sell, but SMS is pushing him to drop the valuation.
