Sassuolo are continuing to negotiate for Borussia Dortmund defender Omer Toprak, claim the latest reports.
The 30-year-old centre-back is under contract until June 2021 and talks have been going for several weeks now.
According to La Gazzetta dello Sport and the Corriere dello Sport, there is now just €1m separating the two clubs and can be whittled down with bonuses.
He joined Borussia Dortmund from Bayer Leverkusen two years ago for €12m.
Although Toprak is a Turkey international, he was born in Germany and spent his entire career in the Bundesliga.
