Andre Villas Boas has reportedly left a piece of paper with his team notes on in the Hotel Vesuvio, which has been picked up by Italian media.
It appears to show that Didier Drogba will not be starting the game and that Gary Cahill will. Ivanovic, Terry, Cole, Essien, Meireles, Ramires, Lampard, Sturridge and Mata are the remaining outfield players.
The authenticity of the leak is not known but, according to La Gazzetta, Napoli's coach is already planning to counter the selection.
It could be a double bluff or a real error from Andre Villas Boas.
