Alexis Sánchez curls the ball into the corner from the edge of the box to put Arsenal in front

Arsenal’s Hector Bellerin speaking to BT Sport: “It’s a new competition for us so we had to set the tone. We think we are one of the best teams in the competition so we have to show that on the pitch.

“I’m very happy for the victory. We were ready to play at eight o’clock, but these things happen. We started a bit with cold feet but after that it just worked.

“The win in the league against Bournemouth and today’s win, coming back from behind, gives you a boost. We will train over the next two days and then be ready for Chelsea.“

Arsenal manager Arsene Wenger speaking to BT Sport: "We had a slow start and there was an accidental goal. After that it was important not to concede and panic and put more pace into our game. From then. we controlled the game and won convincingly in the end.

"I think Sanchez is still running after his best form. He is a fantastic football player but physically he has just come back. But he has it in his locker to do something special, which he did.

"We want to do well in all the best competitions and I had an experienced team today, even though I made nine changes. They are all top class players, there is no hierarchy in the squad."

BUNDESLIGA : Bayern held by Cologne, Chicharito scores as Leverkusen beat Dortmund

Xabi Alonso reacts after Cologne's leveller on Saturday.

Cologne became the first team to deny Bayern Munich victory in the Bundesliga this season as they picked up a deserved 1-1 draw at the Allianz Arena.

Joshua Kimmich gave Bayern the lead five minutes before the end of a first half which the hosts dominated.

It was a different story in the second half, though, with Anthony Modeste bringing Cologne level, and they had the record champions on the ropes but failed to land a winning punch despite going close late on.

The result means both clubs remain unbeaten this season, although Carlo Ancelotti's Bayern left the field for the first time in the league this season without all three points following a previous run of five straight wins.

Javier "Chicharito" Hernandez scored to seal Bayer Leverkusen's 2-0 home win over Borussia Dortmund.

Ahmed Mehmedi opened the scoring after just 10 minutes, heading in Hakan Calhanoglu's cross following a corner, and Hernandez added his fifth goal in the past three games in the 79th minute by turning in another Calhanoglu cross from close range.

Pierre-Emerick Aubameyang thought he'd pulled a goal back with three minutes to play, but it was ruled out for outside.

Dortmund dropped into third place, four points behind leaders Bayern and one back of Hertha Berlin, who earned a 2-0 win at home over Hamburg to spoil Markus Gisdol's first game in charge.

Pierre-Emerick Aubameyang and Dortmund were poor on Saturday, deservedly losing at Leverkusen.
