Arsenal boss Wenger keen on Juventus defender Chiellini
Ranieri wants to be reunited with Gallas, who had a huge public fall-out with Arsenal over his criticism of his teammates.
He is an accomplished centre-back and would represent a significant investment for the future.
The drawback for Wenger will be the asking price. While Gallas, at 31, would cost only £5million, Juventus would want at least three times that figure for Chiellini.
