It's emerged Nice are discussing a loan deal with the Potters for the 24 year-old.
"I remember him at Guingamp, in the days of Jocelyn Gourvennec. After, he went to ... Marseille, yes there it is," began Favre.
"Then to Porto and Stoke now.
"He's a good player, a good left-hander. He can play 6, 8, etc. Now, here he is, we must help a little get him back to his level."
Favre's words suggest a deal is close for the midfielder.
