The Indonesian businessman has revealed he expects significant progress on the deal with the Manchester United captain to be made in the near futureNemanja Vidic's summer move to the Serie A club could be announced in the next few days.
Earlier this month Goal revealed the Serb had informed Manchester United of his intention to join the Nerazzurri, at the end of the season, and Thohir confirmed on Thursday that the deal was "90 per cent done".
And the Inter president has now revealed he expects significant progress to be made in the coming days.
Thohir said: "With Vidic we bring experience: he is after all Manchester United’s captain. In the next few days we will know if it will happen, it would be a great thing.
"I won’t make announcements to ruin the relationship with the club, it will arrive when it’s done.
"Vidic tied to marketing? All of the decisions are collective; when we think of building a team we think of the pitch but also marketing.
"If we can have him it would be good since he is famous in Asia. The Premier League is the top in Indonesia, the player would add value to the club."
Vidic may not be the only veteran to depart Old Trafford as David Moyes continues his remodelling of the United squad, with fellow veterans Rio Ferdinand and Ryan Giggs also out of contract this summer.
