Arsenal manager Mikel Arteta is expecting a major test when they travel to the Etihad to face Manchester City this weekend.
The Cityzens have not made the start to the 2020-21 season they would have liked as they sit 14th in the Premier League table after picking up four points from their opening three.
But Arteta still reckons the clash against Pep Guardiola's side on Saturday will demand a lot more effort from his Gunners because City are "still producing incredible numbers in everything that they are doing".
"I think it will be a completely different game," he said as Arsenal.com reported. "City's approach when they play us will be very different to [Sheffield United's], very different demands for what we have to do with and without the ball as well.
"I am really happy with the way we managed to win the game [agaiant Sheffield United] and how patient we were, and the improvements compared with last year against this type of opposition but again, we know the level of difficulty at Manchester City will be another level.
"They are still producing incredible numbers in everything that they are doing. In my opinion, they have been really unlucky with some of the results they got because they should have put games to bed very early in those games, and then the level of efficiency of the opponents, when they had half-chances, have punished them a lot.
"But I haven't seen any decrease in the level of the way they are playing or in what they are producing game by game. I haven't seen any of that."
