Watching the Arsenal-Burnley match during halftime...the defense is an adventure (and probably will be until Bellerin, Holding, and Tierney are integrated into the lineup...even then it might be a bit rough), but this offense is going to be a problem for the PL. They've been strikingly fluid in transitioning from defense to attack at points, and once you have the full strength attack of Aubameyang, Lacazette, Pepe, Ceballos (plus Bellerin and Tierney contributing from the right and left back positions), we could end up seeing some beautiful offensive football from these guys throughout the season.
