Yes for sure Arsenal is a big team and has not dropped to the extent of measuring with Leeds. The goal margin in the game defined the real arsenal. They have low goals conceded at zero and even at the end of the season it's still possible they would have the most goal difference. However, arsenal has a way of starting each season so well that you would love to hand them over the league title before the last day
 But their attitude of drawing multiple games towards the last week of the league always leaves them at their usual second or third position. If Arteta can learn how to sustain his energy through out the season, arsenal will be winning the league with a high margin. They have played well several years under Arteta but nothing to show. I hope they get it right this time.
