Chelsea have launched a swap bid for Lyon striker, Moussa Dembele.
Sky Sports says Chelsea have made a transfer offer of Olivier Giroud and cash for Lyon striker Dembele.
Lampard has identified Dembele as a target and sees similarities between the Frenchman and his former team-mate Didier Drogba.
Drogba, a prolific finisher and notoriously strong striker, was signed in 2004 for £24million from Marseille and went on to score 164 times in his nine years at Stamford Bridge.
