Former Chelsea player has urged Lampard to sign these two players in the January transfer window.
Formers Blues forward Jimmy Floyd Hasselbaink urges the club to sign two new players in order to win the title this season.
Chelsea are currently fifth on the table, just three points behind leaders Leicester City.
The Blues were one of the biggest spenders in the summer transfer window but Hasselbaink urges the club to sign a defender and a midfielder in the January transfer window.
Hasselbaink told Ladbrokes: “A lot of people are talking about Kalidou Koulibaly 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, 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.”
He continued: “I would also like to see another creative midfielder.
“I like Mason Mount, but maybe somebody to play alongside him. Havertz is there, I know, but you want healthy, quality competition in that area.
“I don’t think Chelsea are far off at all.”
