Martin Odegaard's sweetly-struck free kick on the half-hour mark was all that separated the two sides on the day as Arsenal claimed back-to-back 1-0 wins in the Premier League, but the Gunners' final pass often saw them squander opportunities to add to their advantage.
Arteta has now acknowledged that his side's lack of ruthlessness must be addressed, but the Gunners coach was able to pay tribute to his side for grinding out a "hard-fought" victory.
Speaking to BBC Sport after the game, Arteta said: "It was a hard-fought victory at a really tough place. You have to be ready for a fight. In the first half we had some really good periods when we were really dominant and should have scored more goals. In the second half we gave the ball away cheaply too many times.
"We have players who are not at their strength playing in this type of game, but they did their best and we got the win. I'm very proud of them defensively and I'm really pleased with the win. It's two wins in a row, two clean sheets. Let's go again. We have a lot to catch up!"
The Arsenal coach also claimed that Odegaard is quickly becoming "a real leader" for the North London club after his permanent capture from Real Madrid. body check tags ::
