Fellaini scored in the 28th minute with a left-footed low shot that helped equalise the scoreline after Theo Walcott's goal for the Gunners in the first minute of the game.
The Belgian was at his enigmatic best as he controlled passes with an ease that belied his tall, lanky frame.
Over the course of the current season, he has scored seven Premier League goals and has championed Everton's cause for a top four finish.
Arteta, who played for the Toffees for eight seasons before switching to the Emirates Stadium, was left impressed by his former team-mate's growth as a player as well as his ability to play on the frontline.
"I have seen a tremendous improvement in him, especially in that position," Arteta was quoted as commenting on Fellaini's performance after the game.
"I think it is much more difficult to play against him when he is playing in that forward position around the box. He creates a lot of problems, he uses his size well and he is a threat around the goal, as you can see from his goals.
"For me, he is much more efficient playing there than when he is deeper.He is one of the most difficult midfielders to play against because of his size.
"You don't normally come up against players like that in that position."
Fellaini's future has been the source of much debate as the Belgian international has refused to sign terms on a new deal. It is rumoured that the likes of Manchester United, Arsenal and Chelsea are interested in snapping him up in the January transfer window although the 25-year-old has insisted that he would stay on with the Toffees.
Arsenal next play Swansea at home over the weekend and the Spaniard believes that the competition for a place in the Champions League qualification spots has increased markedly in the current season.
"Tottenham are challenging now, West Brom lost [at Swansea] but have been doing really well and I think Everton have got a good chance if they keep everyone fit," Arteta observed.
"I think the first 11-12 is really strong and they have started the season well, which I know from my time there is not normal. In the long run they will be there."
