Gianfranco Zola: This is who Chelsea must sign this summer

Gianfranco Zola says that signing a defender will be Chelsea's priority this summer

Gianfranco Zola believes that Chelsea must bring in defensive reinforcements in the summer transfer window.

The Blues have been linked with a host of players as Antonio Conte prepares for his first season in charge of the west London club.

Conte has been picked as the man to restore Chelsea to the top of English football after their disastrous campaign under Jose Mourinho last season.

Chelsea are said to be eyeing up a move to make Kalidou Koulibaly Conte’s first summer signing as he bids to shore up his defensive options at Stamford Bridge.

And Chelsea legend Zola feels that bringing in a new defender should be Conte’s priority in the summer transfer window.

Speaking to talkSPORT this week, former Chelsea star Zola said: “I think Chelsea will have a difficult task.

“There will be a lot of competition; much more than in the past. I know Conte and I know Chelsea, it’s a wonderful club.

“But in my opinion, if he wants to play the system that he likes to play at the moment, which is the 3-5-2, then I’m sure he will be looking for defensive positions.”
