Man of the match - Mesut Ozil (Arsenal)

[Titan ;x]

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 scored three times in a game for the first time in his career.

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

The Wenger smile

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

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

Oxlade-Chamberlain might have provided a better finish to Sanchez's beautifully disguised chipped through pass - a second moment of genius on a night the Chilean's 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.

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 from Lucas Perez's cross, and the third was a sweet, low volley that snuck in at the near post, with Perez the provider again.

What they said

Arsenal manager Arsene Wenger, speaking to BT Sport: "Our confidence is stronger with every win but we have to keep the vigilance as well, 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."

What's next?

Arsenal host Middlesbrough in the Premier League in a 15:00 BST kick off on Saturday. Their next match in the Champions League is the return fixture against Ludogorets in Bulgaria on Tuesday, 1 November.
