The Belgian keeper is preparing to face city rivals Real in Saturday’s Champions League final in Lisbon, who defeated Pep Guardiola’s Bayern convincingly to set up an all-Madrid showdown. Carlo Ancelotti’s team earned a 1-0 win in the first leg in Madrid and followed it up with a 0-4 away win at the Allianz Arena against the reigning European champions. Courtois believes his side can learn from Borussia Dortmund’s performance against Real, when two Marco Reus goals gave them a 2-0 win over Los Blancos in the quarter-final second-leg. We should learn from Dortmund’s second-leg display against Madrid. They showed how it’s done,” said the 21-year-old. The youngster then went on to say that Guardiola’s tactics were nave as his opponents knew what to expect from the former Barcelona manager. Bayern’s tactics were silly. They copied Barcelona’s style of play and Madrid know all about this philosophy,” he told Sport Bild. Their players only need a few seconds to cross the entire pitch. They have the perfect weapon against possession-based football, Courtois added. The Belgian is on course to win the award for fewest goals conceded in the Champions League, of the keepers who have competed in over 10 matches, having let in just six goals.
