Half-time: Chelsea 0 Real Madrid 3
Marcelo scored twice in a one-sided first half in front of a crowd of more than 105,000 at Michigan Stadium.
Real Madrid took the lead in the pre-season friendly when Marcelo’s 20th-minute shot took a deflection off Oscar, wrongfooting Chelsea keeper Asmir Begovic.
There was nothing fortuitous about the Brazilian’s second goal six minutes later.
He pounced after Blues youngster Ola Aina gave the ball away, rode a couple of weak challenges and thumped home.
With Real dominant, Begovic produced good saves to keep out Raphaël Varane’s header and Casemiro’s stinging drive.
But Begovic could do nothing about Mariano Diaz’s breathtaking 30-yard strike which put the Spanish side 3-0 up eight minutes before the interval.
Chelsea: Begovic, Aina, Cahill, Terry, Azpilicueta; Oscar, Matic; Willian, Traore, Loftus-Cheek, Pedro.
