"Overall we dominated the game and had the better chances but Everton are a good side and when they broke in the first half they scored a goal. Overall we are happy to be at Wembley," Arteta told ITV1.
Of his penalty, the Spaniard said: "It was a massive moment but I'm happy that I scored.
"It was (a turning point). We knew they had to attack and on the break we would have the chances to score and we took it.
"It would be amazing to (win). We have a good chance. We're in the semi-final at the moment."
