Paolo Di Canio is wondering how Eden Hazard can flourish under Maurizio Sarri's football style.
The former Sunderland boss says Antonio Conte's successor will have to get the best out of the Belgium international - who is heavily linked with a move to Real Madrid following striking displays at the World Cup this summer.
"I'm wondering if he [Sarri] will be able to bring his idea of football," Di Canio told reporters as AS.com quoted.
"He needs to improve in the management of the world-class players who don't want to be closed in a specific role.
"For example, a player like Hazard wants to play free on the pitch but we know that Sarri wants players to respect a specific role on the pitch. Sarri will need to work on it."
