Former Premier League midfielder Danny Murphy believes Maurizio Sarri would have to improve Chelsea’s defence if the Blues are to win trophies under the Italian.
Murphy also admits scoring goals won’t be a problem for Chelsea under Sarri.
“Sarri is a manager who has a huge reputation for bringing goals and I can see that following him to Chelsea,” Murphy told Bwin.
“I think [Alvaro] Morata and [Olivier] Giroud have the potential to score 20 Premier League goals this season if they both play regularly.
“I look at [Eden] Hazard and how he played at the World Cup and I think he also has the potential to score 20 Premier League goals in a season.
“Sarri is looking to implement a very attacking style, but I think we’ve already seen how easily Chelsea can be opened up and their defensive frailties this season.
“Chelsea would never get opened up so easily under Conte and [Jose] Mourinho so that’s a balance that needs to be addressed if the club is to be successful.
“You can’t win trophies if you’re leaking goals.”
