Since taking charge in 2019, Arteta has made a point of reiterating how much he values physicality and the demands he puts on his side to win duels.
But against Brighton, Arsenal were dominated all over the pitch and lost challenges which they would usually be expected to win.
Arteta said he was “extremely disappointed” as his side were “very far” from doing the basics he expected, with uncertainty in defence, a loss of midfield control and lack of attacking creativity.
Asked why they were below par, the Spaniard added: “Well, the first one because Brighton they were really good, and they had another bite, and at the times it was better.
“There are a lot of moments when the ball is 50-50 and it changes hands and most of the time it was for them.
“Sometimes there were some technical errors very much involved that opened us up in a really difficult way, but that’s something to learn.”
He was quick to remind the media in his news conference after the game that it was still a good start to the season.
The Gunners had 15 players at the World Cup which meant that a large part of the squad joined up for pre-season later than the rest of their team-mates.
“That’s not going to take away what the team has done and the boys have done in the last six or seven weeks since coming back from the World Cup,” added Arteta.
“What we’ve done and the way we’ve competed and the amount of games we’ve won has been remarkable, but this is a big lesson for all of us to understand what it takes to win at this level.”
