The Blues, who are expected to sell Diego Costa this summer, have reportedly agreed personal terms with Lukaku.
Wilkins told Sky Sports: "If you look at Chelsea over the last x amount of years, you've had the Drog,"
"They will never find another Drogba, he was the best.
"Then they had [Diego] Costa and now Lukaku just is a perfect fit.
"If Costa was to go I think he would be the perfect fit to come into Chelsea."
