The Sky Sports Spanish football expert believes that Mourinho would be happy to let De Gea leave for the Bernabeu for £22m plus Morata.
Balague wrote on Twitter: "Morata said last night his dream is to stay at Madrid… but he's looking for a way out. Nothing from Milan at this point, MUFC want him.
"Mourinho (strangely) willing to sell De Gea for €25m and Morata. Chelsea divided between Lukaku & Morata. He would like to play in the PL."
United are in the market for a striker given the uncertainty over Zlatan Ibrahimovic's future.
