Gianfranco Zola was sorry to see Juventus sack Maurizio Sarri.
The pair worked together at Chelsea and won the Europa League.
“I'm a little sorry for him and his group, I worked with hem for a year at Chelsea and it was very important for me," said Zola.
“We talked about it with Maurizio, that Juventus are a demanding team and sometimes it's not even enough to win.
“There are many requirements that must be met."
