The Gunners found themselves 2-0 up after 26 minutes but were pegged back by the Bundesliga side, leaving the Gunners in second place in Group B and only a point ahead of Olympiakos.
“Considering that we were 2-0 up it can’t be a good point for us,” Arteta told Sky Sports. “We were unlucky to concede the first goal just before half time. But before the game, a draw here? It’s not an easy place to come.”
The visitors took the lead in the 18th minute when Theo Walcott bundled his way through on goal and tucked his effort away after Olivier Giroud made a hash of his shot.
And Giroud then doubled the Gunners’ lead eight minutes later when he ghosted into the six yard box and headed home Lukas Podolski’s cross.
However, Schalke halved the deficit on the stroke of half-time when Klaas-Jan Huntelaar fired his shot past Vito Mannone after being found by Lewis Holtby.
And the Bundesliga side rescued a point in the 67th minute as Jefferson Farfan’s shot was deflected into the net by Thomas Vermaelen.
Arteta admitted that conceding a goal just before the break took the wind out of the Gunners’ sails.
“It was [a hammer-blow for us] because it made it a completely different game,” he continued.
“It was tough to be honest, they put a lot of pressure on us. We played a bit deep in the second half. When we broke we had some chances to score but in the end we got the draw.”
Arsenal boss Arsène Wenger said: “I believe 2-2 is fair. At 2-0 you have not won the game in the Champions League, especially with the physical quality of the German teams.
“I didn’t feel the game was over at 2-0. We lost on Saturday and at least we didn’t lose the game today.
“What is important for us is to win the next game at home against Montpellier and see what happens here.”
