Jamie Vardy scored once again against the Gunners to seal the Foxes’ first league victory in the Emirates in 47 years.
The diving header for the second half came after Alexandre Lacazette had his own header ruled out for offside.
That initial incident happened in the first half, 45 minutes in which the Gunners had their own chances. But Arteta admitted his decision to “attack” space in the second half was the downfall of his team.
“To be honest, I was really happy with the first half. The way we exerted pressure and the aggression we showed ”, spanish said (via football.london).
“We’ve been efficient with that and we’ve limited them to nothing. We scored the goal from a set piece and I don’t know how it was disallowed.
“We had to be patient and not make a mistake, we made the decision when there is no pressure on the ball to try to attack that space and they scored a good goal.
“We didn’t manage to have enough continuity in our game, we didn’t put the ball as often as possible in the box. It’s a very hard result for us considering what happened in the game.
LacazetteThe goal was ruled out after Granit Xhaka was put on trial for hindering Leicester goalkeeper Kasper Schmeichel as the header shot through the box.
Arteta admitted he felt frustrated with the decision to cancel the goal, which had a “massive” impact.
