AJ is good enough to play against the weaker PL teams, but you have to be joking if you think he is one of our best 3 attacking players.
I hope he will be great in a couple of years time, but right now he has a lot to learn.
He scored a great goal today, but he wouldn't have been able to do that against a good defence. Look at what else he offered: He dribbled the ball out for a Newcastle throw in, he ran to the by-line and lost it, he offered no attacking support to Silva, and when the attack broke down, he offered no defensive support to Boateng.
Look at the whole picture please, don't get silly. He is still just one for the future.
