Marchisio believes that Giorgio Chiellini's sending-off proved to be the decisive moment in that match, declaring that Juve can test Carlo Ancelotti's side if they maintain a disciplined approach.
He told AS: "We have to pay close attention to Madrid's counter-attacks. We have to keep an eye on players like Cristiano Ronaldo and Gareth Bale, who are very quick When they come out on the break.
"They have plenty of strong players up front, but they sometimes help out less in defensive areas, putting Their backline under pressure."
"But the reality is that real Madrid have great players and are on the way to becoming a terrific team under Ancelotti, who is a good coach."
Antonio Conte's side are still searching for the first win of the campaign in Europe, with the Madrid defeat preceded by draws against Copenhagen and Galatasaray.
