Chelsea are being urged to consider Spartak Moscow striker Quincy Promes.
The young Dutchman is well known to Blues boss Guus Hiddink and is in a rich vein of form.
Former Spartak defender Evgeny Lovchev told Sovsport: "He would be especially useful for Chelsea.
"He has speed, an individual trick, a good pass, makes goals and can play at any level.
"In Chelsea there is Guus Hiddink and that man knows the qualities of the player."
