London, February 22:

Thierry Henry scored in Arsenal’s 1-0 upset win at Real Madrid in the Champions League on Tuesday, while AC Milan ended Bayern Munich’s 15-match winning streak at home with a 1-1 draw. Europe’s top club competition resumed after a 2 1/2-month break this week with the first leg of the opening knockout round. In other matches on Tuesday, defending champion Liverpool lost 1-0 at Benfica and Lyon won 1-0 at PSV Eindhoven.

Arsenal traveled to Madrid with a youthful defense, without the experienced Dennis Bergkamp and low on confidence after its poor recent record. But the Gunners had three chances to score in the opening 10 minutes - Jose Antonio Reyes, Fredrik Ljungberg and Henry all going close.

Henry scored in the 47th minute, eluding four defenders to net past Madrid goalkeeper Iker Casillas. It’s the first time an English club has won at Madrid’s Santiago Bernabeu stadium.

Six-time champion AC Milan played five-time winner Bayern Munich in Germany.

Michael Ballack gave Bayern the lead in the 23rd minute with a right-footed shot. Milan leveled in the 58th when Valerien Ismael handled the ball and a penalty was awarded. Andriy Shevchenko scored by sending Bayern goalkeeper Michael Rensing the wrong way. Regular goalkeeper Oliver Kahn warmed up but didn’t play because of a bruised thigh. Milan and Bayern have met three times - in 1968, 1990 and 2002 - and each time the Italians have advanced.

Bayern moved into Allianz Arena this season - a 70,000-seat stadium that will host the World Cup opener - and had won all of its previous 15 matches there, including Champions League games.

Benfica’s Brazilian defender, Luisao, scored six minutes from the end in Lisbon, Portugal. Luisao beat his markers to head home a free kick from Armando Petit when the game looked headed for a draw. Liverpool captain Steven Gerrard, who has a minor knee injury, came in as a late substitution.

In Eindhoven, Netherlands, Lyon’s Juninho scored in the 65th minute from a free kick. His winner curled toward the middle of the goal and PSV keeper Gomes misjudged the flight for it to bounce in off his thigh.
