Toure is widely expected to move to the Barclays Premier League, with Manchester City the favourites to land the Ivory Coast midfielder who is currently on World Cup duty with his country in South Africa.
Dimitri Seluk claims the Nou Camp exit door is moving ever closer for the 27-year-old, although he confirmed he would nevertheless seek talks with new Barcelona president Sandro Rosell in the coming days.
"I think we will probably close his departure very soon. It is likely to be this week, but at the moment we can't announce anything," Seluk told Com Radio.
"I haven't spoken to Rosell, but out of respect of course I will speak to him before anything is closed.
"[Joan] Laporta is the president until June 30, but I have to speak to Rosell and know his opinion because he is the new president."
