Arsenal hero Nigel Winterburn felt squad depth and personnel made the difference for Manchester City in midweek.
City won 3-1 at Arsenal to take the Premier League leadership on goal difference, though having played one game more.
Asked if City manager Pep Guardiola had outcoached Mikel Arteta, Winterburn told Tribalfootball.com: "I think what we all know is that Manchester City have more options off the bench than Arsenal.
"Manchester City have the ability to change things if someone isn't performing, Arsenal are improving their squad to have options as we've seen in the recent transfer windows.
"I believe Arsenal will buy again to make themselves stronger, but there isn't a comparison right now because Manchester City have an unbelievable amount of strength in the squad. You could say that Pep should be able to change games more regularly than Mikel Arteta can do.
"Arteta has made good changes, he has Trossard to lean on who came off the bench to score against Brentford.
"It didn't turn out to be the winning goal, but Arsenal are starting to get players in who can come on and change things.
"It's a squad now challenging for positions week in week out, but it still needs adding to. Mikel Arteta will know that and if you ask him at the end of the season he would agree with that statement."
Winterburn, however, also insisted Arsenal had created enough chances to win on the night.
On behalf of OLBG, Winterburn told Tribalfootball.com: "Manchester City did defend well because Arsenal only scored once.
"But I could name you a couple of opportunities that Arsenal had where on another night they would take them.
"Eddie Nketiah had at least two chances where he could have done better, so if they go in you can say Manchester City don't defend as well as people think.
"But because Manchester City took their chances, we're now saying Arsenal didn't defend as well as they have been doing. It comes down to those fine lines, what we know about this Manchester City team is that if you switch off for a second, then they score.
"Usually, they have more possession of the ball then anyone which gives them more opportunities, obviously last night they didn't but still managed to score three goals themselves.
"That's what Manchester City can do to teams."
