Unai Emery claimed that Arsenal were unlucky to suffer a 1-0 defeat at Sheffield United as Lis Mousset condemned the Gunners to their latest away flop on Monday.
Emery's side have been without a Premier League victory since the opening weekend of the season, which failed to raise the challenge United held at Bramall Lane.
French forward Mossett scored his second goal for United when he made his first Premier League debut, signing Bad Arsenal in the first half and signing with Bournemouth.
That was enough to send Arsenal to their second defeat of the season to end an eight-game unbeaten run in all competitions.
The North Londoners are fifth in the league after a powder-puff performance that showed Emery's rebuilding work which is still in progress.
But Emery insisted that Arsenal are the least attracted and criticized the failure to pay a fine for dishonesty on Socrates.
"We didn't deserve to lose. We can talk about two key moments, one is the goal and the other is a clear penalty with Socrates. With the VAR, dishonesty should have been reviewed, but we had to accept it. Will, ”Emery said, extended to 26 years following Arsenal's victory in the city of Sheffield. "We had more opportunities than that. If we scored a goal, we could control better. "
Asked if Arsenal have a mental barrier in the away games, Emery said: “We prepare for the same home and away matches and look to win.
"We were more qualified but they are a very strong defensive team."
Under Emery, Arsenal have kept just two clean sheets in 24 away league matches and once again they easily end up in a hostile environment.
He said, & # 39; We gained a lot of lead in the first half and scored. This might be possible. Above all, we have to improve by not allowing that kind of balls, ”said Emery. "We are playing some young players who are taking experience but winning is the most important."
It was a signature win for the Blades following promotion from last season and they proudly sit in ninth place, just three points behind Arsenal.
With the crowd at Bramall Lane in full voice, a gruesome struggle kicks off to a controversial start, when Socrates appeals in vain for punishment after John Egan embraces his shirt.
Amide's men should have taken the lead when Saeed Colasinac crossed a perfect low cross towards Nicholas Pepe in the box six yards, but the unmarked Ivory Coast winger missed his shot completely.
It was the latest in Pepe's growing list of disappointing performances, which have struggled to make an impact since moving their club record to Leila's close season.
United revived Arsenal's long-running set-piece issues in the 30th minute.
Oliver Norwood's corner reaches far away Jack O & # 39; Connell and he moves over Metset Gendaugee to Mousset, who pokes home from the line after Granit Xhaka fails to respond to the threat .
Strongly, Arsenal have conceded 22 league goals from set plays since the start of last season, with only Watford (25) and Everton (24) allowing more.
Xhaka almost handled an equalizer with a long-range effort that was pushed into full stretch by Dean Henderson.
Mesut Ozil was once again left out of the Arsenal squad and Pierre-Emerick Obemayung's anonymous, Emery was sent over to Dani Cabellos, but he shot weakly at Henderson from Bukayo Saka's cross.
Alexander Lacazette came on for his first appearance 22 minutes after suffering an ankle problem that ruled the Arsenal striker since early September.
For all their regional dominance in the closing stages, Arsenal were lacking in the final third.
Pepe only touched wide and Kolinasak, as the visitors' treachery was laid bare.
