Lazio are fearful that they might be powerless to losing Sergej Milinkovic-Savic.
The midfield sensation has emerged as a transfer target for Manchester United as Ole Gunnar Solskjaer looks to bolster his ranks for the new season.
Bruno Fernandes had looked to be the man likely to fill the midfield void, but Milinkovic-Savic was recently suggested to be an alternative option.
United have been linked with the Spanish-born Serbian star in the past but they might have a better chance than ever to get the deal done this summer.
Lazio president Claudio Lottito has given United hope that an agreement could be reached with his latest comments.
“We’ve created a glasshouse, where it’s understood that people can’t be forced to perform their roles in an environment where they feel cramped,” Lotito told Corriere dello Sport.
“Milinkovic has shown sincerity and responsibility, so that isn’t the case with him. He feels good here.
“Last year I managed to resist the assaults of other clubs, but this year I’d have fewer weapons if a different solution was proposed to the player.
“Let’s say that I used up some of my weapons last year.”
United are desperately looking to improve their midfield after losing two central players in the past six months.
Earlier this year, Marouane Fellaini left for the Chinese Super League, while Ander Herrera left the club to join Paris Saint-Germain last month.
Last summer, United were put off by Milinkovic-Savic’s £87million price tag but a deal could be struck for less if he tells Lazio that he wants to leave.
