The Ghanaian joined Sassuolo because his wife wants him to be closer to the family.
The 31-year-old after spending just a season with Eintracht Frankfurt, helping them win the DFB Pokal has switched camp to Sassuolo to seek new adventure.
The decision to return to Italian football came a surprise to many as it appeared he had settled extremely well in Germany.
But Managing Director of Frankfurt Fredi Bobic has revealed the Ghanaian opted to return to Italy to get closer to his family.
" He called me telling me to have the opportunity to get closer to the family, who is in Milan. I could not hold him back, it's a choice of life," Bobic said
"One would have gone to America, China or Qatar for money, but he did not do that. He has to be praised.
"Boateng can help to grow young people. I was also impressed by his effort in the fight against racism."
Boateng is married to Italian super model Melissa Satta and have a son together Maddox.
