The Gunners have reeled off three straight league wins for the first time this year and scored seven goals in their last two away games.
But a glance at the league table even at this early stage, with unbeaten leaders Manchester City five points better off, leaves Wenger and everyone else off the current pecking order.
“At the moment, they are the better team as well as the most consistent,” he said.
“We have to play catch-up a little bit but hopefully we can do that – last year City won their first five games.”
Arsenal were always in control against a spirited Hull side and the result was never in doubt once Jake Livermore was sent off just before half-time.
Now Wenger is looking for the Gunners to up their game at home as well.
“Away from home, we look more convincing,” he said.
“I believe when we lost our first game (against Liverpool), it was a mental shock for us and for our supporters and straight away, you have a little bit of scepticism and doubt in your head.
“So it was important to beat Southampton and hopefully, now we can produce the same quality at home.”
If Wenger isn’t getting too enthused about Arsenal’s title prospects, the form of 20-year-old Alex Iwobi offers real hope.
Though Alexis Sanchez (2), Theo Walcott and substitute Granit Xhaka were the goalscorers with Robert Snodgrass replying from the penalty spot, Iwobi was the real star of the show.
His sublime back heel, which paved the way for Walcott to open up a two goal lead 10 minutes into the second half was the magical moment of a game in which Arsenal hovered between mesmerising and sloppy.
Wenger sees no reason why Iwobi can’t scale the heights his uncle Jay Jay Okocha did for Bolton.
“He’s a good example to follow,” said the Frenchman. “You’ve seen his qualities, which I don’t really need to describe but what I really like is his love for the game, his passion and his hard work.
As he approaches his 20th anniversary in charge at Arsenal, Arsene Wenger is far too long in the tooth to become embroiled in mind games with his managerial rivals.
As he spoke of Manchester City’s impressive start to the season, he was stating facts, not putting pressure on the Premier League leaders.
But he was the first manager to articulate what has looked increasingly clear with each passing game: Arsenal, and the rest of the Premier League, are playing catch-up.
While Arsenal continued to repair the damage inflicted by their two-game no-show at the outset of the campaign, Pep Guardiola’s men underlined their status as the eminent force in English football. They recorded an eighth consecutive victory in all competitions.
City enjoy a five-point advantage over the Gunners, who must wait until they travel to the Etihad Stadium, in December, to test themselves against a side already being talked of as champions-elect. Until then, it looks like a case of attempting to hang onto City’s coat-tails.
