Chelsea legend Jimmy Floyd Hasselbaink is a huge admirer of Leicester City center back Caglar Soyuncu.
Hasselbaink believes that if Blues boss Frank Lampard was to go back to the transfer market to sign a centre-back, he should consider the Turkey international.
The Blues have improved defensively with the addition of veteran Thiago Silva, but he is not a long term solution in the position.
Hasselbaink told Ladbrokes: "A lot of people are talking about Kalidou Koulibaly [from Napoli] but he's 29 years old and would be very expensive.
"I actually quite like the Leicester defender, Caglar Soyuncu. I think he'd be very good at Chelsea.
"Also the defender at Inter, Milan Skriniar - everybody is talking about him, another very good player.
"So there are players out there, but it's such a difficult position to fill at the moment."
