The 23-year-old Guinea international has been a revelation in his first season in Serie A.
"It's an honour, a real pleasure.
"Knowing that I am being linked to such an important club gives me great satisfaction.
"In my heart, I hoped that I'd have a season like this one, but it was a hope.
"To have managed to do it really is something else. I am happy.
"We'll think about the future later. Chateauroux still own my contract, but Chievo will exercise their option to sign me."
