Everton boss Roberto Martinez says there's a lot of improvement left in his team.
The one-sided nature of Everton's triumph over Arsenal, but for Martinez it was just another step closer to his ideal of the perfect performance.
"We all know that it's difficult to get perfection in football terms," he told the Liverpool Echo. "There's always slight margins for improvement.
"Especially when you have two distinct groups of players like we have; an experienced group with incredible standards who have been through everything, then the young group who have that unknown quality but also require hard work every day to fulfil their potential.
"I still feel we haven't fulfilled that potential."
