Arsenal 6-0 Ludogorets Razgrad

Alexis Sanchez has been involved in four of Arsenal's Champions League goals this season, scoring twice and assisting twice

Mesut Ozil scored a hat-trick after stunning goals from Alexis Sanchez and Theo Walcott as Arsenal dismantled Ludogorets Razgrad in a ruthless Champions League display.

Sanchez got the first with a masterful chip from just inside the box.

Walcott powered a curling shot home after Ludogorets' Wanderson hit a post.

Alex Oxlade-Chamberlain smashed a loose ball into the corner for the third, before Ozil claimed the first hat-trick of his career.

The Gunners have won seven games in a row in all competitions - scoring 23 goals - and are unbeaten in 11 matches.

Their last defeat was at home to Liverpool on the opening day of the Premier League season.

Victory over Bulgarian champions Ludogorets means Arsenal top Group A ahead of Paris St-Germain, who beat Basel 3-0, on goal difference.

Wenger is smiling...

As Sanchez's drifting lob settled in the Ludogorets net, gleeful manager Arsene Wenger leapt from the bench in celebration. It was just the beginning.

The Frenchman's side were so dominant and full of confidence they perhaps should even have won by a greater margin.

Oxlade-Chamberlain certainly might have provided a better finish to Sanchez's beautifully disguised chipped through pass - the Chilean's second moment of genius on a night his hard running and quick mind came to the fore.

But the player who most obviously embodies Arsenal's new dynamic mood is Walcott. He impressively put two earlier missed chances out of mind when doubling the lead with a powerful strike that signalled the away side's slide towards heavy defeat.

It was the 27-year-old's seventh goal in his past six Arsenal games, having scored the same amount in his previous 42.

For 60 minutes, Walcott and Sanchez terrified the opposition backline with their pace, and he went off to huge round of applause when he was replaced by Lucas Perez.

There were big smiles as he took up a seat on the bench - from both Walcott and Wenger.

...but there's still much to do

In each of the past six seasons, Arsenal have fallen at the first knockout stage, the last 16. In all but one of those seasons, they finished second in their group.

With Swiss club Basel and Ludogorets six points adrift with three matches to play, Group A will surely be won by Arsenal or French champions PSG.

The Gunners began their Champions League campaign with a battling point in Paris, and the two teams meet in north London on 23 November.

Wenger told BT Sport: "Let's qualify first. We go to Ludogorets in two weeks and they will want to show us they are better than 6-0, but if we win there it would come down to the game against PSG."

Man of the match - Mesut Ozil (Arsenal)

"Boom Bam Arsenal! Brilliant team performance and very happy about my first ever hat-trick!" Ozil wrote on Twitter

Sanchez was a close contender (the brilliant goal, determination and beautiful footwork) but this has to go to Ozil.

Having earlier assisted Walcott with a pin-point pass to the edge of the area, the Germany international fired in three excellent close-range finishes in just over 30 second-half minutes.

The first was a cool, calm finish with plenty of time to pick his spot after Santi Cazorla's ball over the top, the second he slotted home from Perez's cross, and the third was a sweet, low volley that sneaked in at the near post, with Perez the provider again.

What they said

Arsenal manager Arsene Wenger: "Our confidence is stronger with every win but we have to keep the vigilance and the urgency to bring that into the next game.

"Let's not be too quick on the verdict. We have a strong squad and a strong spirit, but you have to take care of it and keep your feet on the ground. The only way to win something big is to focus on the next one and work on humility.

"I feel that at the moment because we win game after game our confidence is high. Maybe we get over dodgy periods with less psychological damage.

"In the first half, it looked like a difficult game because they were dangerous going forward; they had good technique in short space; they are quick on the counter attack.

"I believe it was not easy but in the second half we took complete control of the game. I think we could have scored more."

Former England defender Rio Ferdinand on BT Sport: "I want to see [Arsenal play like this] for a sustained period of time.

"They always make you think they've got a chance, and then they let you down.

"Now they have to take things game by game, get through Christmas with this kind of form, and then you can start really judging them as a team. They need to win something."
