Roberto Di Matteo has shortlisted two wingers from Porto and Lazio as he rejigs his squad in the absence of Didier Drogba.
It could also mean £50 million Spanish star Fernando Torres playing up front as the solitary striker in a 4-5-1 formation.
The new Chelsea boss also wants to beef up competition by providing back-up to Branislav Ivanovic and Ashley Cole.
Di Matteo is seeking a right-back, a versatile left midfielder-cum-defender and a replacement for Didier Drogba as top of his list of priorities, according to the Daily Mail.
Two names near the top of his shortlist are Porto's Cristian Sapunaru and Senad Lucic from Lazio.
Sapunaru is seen as being able to provide cover for Ivanovic ahead of what is sure to be a testing campaign for the Champions League winners.
And Bosnia international Lucic, who has enjoyed an excellent first campaign with Lazio, has the added attraction of being able to play either as a wide midfielder or at left-back.
