Gary Neville has paid tribute to Arsenal's defensive organisation, speaking after their win at The Etihad to SkySports.
The Gunners won 2-0 thanks to goals from Santi Cazorla and Olivier Giroud in either half, and City rarely threatened.
The solidity at the back was notable as it was with regular right-back Mathieu Debuchy out injured.
Neville admitted he did not expect Arsenal to win, but welcomed the improvement in their organisation. He even went as far to describe the display as among the best he has seen from a defensive perspective.
He said: "I was wrong and I’m happy to be wrong, we’ve seen so many examples over the last four or five years of Arsenal capitulating that if you offered me the opportunity to come back as an Arsenal defender, I would have said no. It wouldn't have been much fun.
"Today, the defenders were never exposed; it was one of the best back-four performances I've seen.
"Koscielny and Mertesacker probably aren't as tired as they've ever been. They were calm, relaxed, composed and didn't look in any trouble towards the end of the game."
That's huge praise from Neville, who so often along with ex-Liverpool defender Jamie Carragher has torn Arsenal's defending to shreds in his analysis on SkySports' Monday Night Football, notably their 3-2 loss at Stoke.
Neville said after that game Arsenal's defending was 'unacceptable', and 'made his blood boil', reported London24, with Mertesacker singled out for criticism by Carragher.
It may however be safe for the German to watch on Monday night, and take in the plaudits.
