MADRID, Oct 23, (Agencies): Real Madrid came back from 2-0 down at home to Borussia Dortmund to win 5-2, while Girona beat Slovan Bratislava 2-0 to claim its first-ever points in the competition in Spain.

In a repeat of last season’s final, Dortmund rocked Madrid with two goals in four first-half minutes. The first goal came in the 30th minute when Donyell Malen side-footed past Thibaut Courtois after a magnificent pass from Serhou Guirassy. Four minutes later, Jamie Gittens took advantage of a lack of upfield pressure to net the second for the German side after it was allowed to advance, and Donyell Malen crossed to the far post.

The goals woke Real Madrid up, with Jude Bellingham heading into Gregor Kobel’s arms before he and Vinicius hit the Borussia woodwork within seconds. Real Madrid kept the pressure on at the start of the second half and got back into the game thanks to Antonio Rudiger’s powerful header after 60 minutes. It was level two minutes later when Kylian Mbappe and Vinicius Jr combined to have a simple tap-in. Serhou Guirassy saw a shot saved by Thibaut Courtois’ legs moments before Lucas Vazquez scored the winning goal for Real Madrid with a powerful right-foot shot after the ball fell kindly for him in the penalty area off a defender.

Vinicius Jr added a fourth for Madrid in the 86th minute after a run from deep inside his half to then score with a right-foot shot and rounded off the scoring in injury time with another individual goal as he turned the Dortmund defense inside out. Miguel Gutierrez put Girona ahead close to halftime with a left-foot finish after good work from Arnaut Danjuma down the left wing.

Juanpe doubled Girona’s lead with a perfect free kick in the 73rd minute. The defender’s shot went over the wall to leave Slovan goalkeeper Dominik Takac with no chance. Cristhian Stauni could have added a third from the penalty spot, but Takec blocked his effort magnificently.

Three straight wins, no goals conceded and top of the league on maximum points. Aston Villa’s first-ever Champions League appearance couldn’t be any better. Villa’s 2-0 home win over Bologna on Tuesday maintained the 100% start to the English team’s first campaign in Europe’s top club competition since 1983 - when it was called the European Cup, which Villa won in 1982. Villa opened with a 3-0 win at Swiss outsider Young Boys and then beat German giant Bayern Munich 1-0 in its first home game of the revamped competition.
