The West Ham manager was voted as the all time greatest player at Chelsea.
“I think Chelsea will win but only just,” Zola told Tuttosport.
“I think the match between the Blues and Bianconeri will be very interesting.
“On one part there is the prestigious Chelsea of my career and, on the other, you have Claudio Ranieri who gave me so much. I am sure the game will give some good and spectacular for everyone.
“I think it will all come down to whoever is in the best form physically.”
