The report suggests that should Jose Mourinho decide not to let De Gea move to Madrid, Los Blancos will then turn their attention to Chelsea keeper Thibaut Courtois.
The Belgian would cost Real £60m, with the fee being used by Chelsea to purchase Atletico's Jan Oblak. The Slovenian's departure would push Diego Simeone to search for a replacement, which the report believes could be Napoli's Pepe Reina.
The Serie A club would then move for Arsenal loanee Wojciech Szczesny, who has impressed in his loan spell at Roma. The Gunners would sell for the right price, leaving Roma with a void that they would fill by recalling Lukasz Skorupski from Empoli.
