Mesut Ozil says the key to scoring his first goal of the season was staying "ice-cold".
The Germany international opened the scoring at Villa Park, slotting past Brad Guzan after latching onto Danny Welbeck's piercing through-ball.
Ozil and Welbeck combined to devastating effect at Villa Park. Ozil was delighted both to score himself and to set up Welbeck's first Arsenal goal.
"I think when you assess [Welbeck's] pass, it was really well timed," Ozil told Arsenal Player.
"He saw me and played me through to finish. I didn't have to do that much because I was one-on-one against the goalkeeper and made sure that I stayed ice-cold in front of goal – that was that.
"When you analyse [Welbeck's] game, you notice that he makes a lot of runs and knows where he needs to be. We're pleased to have a striker like him here. He makes the game simpler for us through his runs and speed.
"[On Saturday] he proved again that he is very dangerous in front of goal and personally, I'm happy for him because in recent games, he missed a few chances. Things worked really well for him on Saturday and that's why I'm pleased for him."
