Former Italian forward Paolo Di Canio has warned his compatriot Maurizio Sarri that he will have to change his tactics in order to extract Eden Hazard’s full potential at ChelseaThe 27-year-old had an outstanding World Cup campaign for Belgium this summer and captained the national side to a third-place finish in the competition, which is highest the Red Devils have ever reached.Three goals and two assists in six games saw Hazard being awarded the Silver Ball award, which goes to the second-best player of the World Cup.But whether he remains a Chelsea player come the end of the summer transfer window on August 9 remains to be seen, although Sarri is hopeful that he can convince the Belgian to remain at Stamford Bridge and he revealed it would be a pleasure for him to make Hazard an even better player than what he already is.However, for Di Canio, the main concern that Sarri should be focusing on is how he can make the free-spirited Hazard prosper under his rather rigid style.“I’m wondering if he [Sarri] will be able to bring his idea of football,” said Di Canio, according to SportsKeeda.“He needs to improve in the management of the world-class players who don’t want to be closed in a specific role.Jose Mourinho is sold on Lampard succeeding at Chelsea Tomás Pavel Ibarra Meda – September 14, 2019 Jose Mourinho wanted to give his two cents on Frank Lampard’s odds as the new Chelsea FC manager, he thinks he will succeed.There really…“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.”Sarri nearly led former club Napoli to their first Serie A title in 28 years last season after finishing just four points off winners Juventus and Di Canio reckons that the 59-year-old fully deserves the opportunity he has at Chelsea.“I’m happy [for Sarri] because he deserved it [to be the manager of Chelsea],” said Di Canio. “He paid his dues.“He arrived in Napoli where he got lot of points and he was so close to interrupting the domain of Juventus. Now, he finds himself into another reality.“I don’t want to compare Napoli with Chelsea, but Chelsea are a world-class club in terms of organisation. And the Premier League is the best football league in the world.”Di Canio used to play in the Premier League for Sheffield Wednesday, West Ham and Charlton Athletic.
