Asking a Chelsea supporter to name the Blues' best ever signing is a difficult task. Chelsea have made some outstanding additions who have played integral roles in the club's success, particularly during the Roman Abramovich era.
Frank Lampard, Gianfranco Zola and Didier Drogba would all be popular choices, but Chelsea have been told that they if they can get one particular deal over the line, it would be their biggest signing in the last 50 years. However, the person in question isn't Aurélien Tchouaméni, Rafael Leao, Frenkie de Jong or any other high-profile player linked with Chelsea.
Todd Boehly has been told that hiring Christoph Freund as the Blues' new sporting director would have been a 'sensational' signing.
