2. Walcott adds another string to his bow
There are many Arsenal players in sparkling form who deserve special mention for their performances. Sanchez looks released and rampant up front. Oxlade-Chamberlain put in a brilliantly complete display. Ozil was gloriously gliding all over the pitch.
Those are all qualities we've seen before, though. What we haven't really witnessed is Walcott scoring a long-range goal like he did against Ludogorets.
Sure, he might have been a little fortunate that the goalkeeper was left grasping at his shot, and it maybe could have been placed better, but the key point was the confidence to try it. It is just not something we're used to seeing from Walcott, who seems to score only certain types of goals.
Sources close to Walcott say he became determined to improve all aspects of his game in the summer, particularly in terms of his shape and physicality, and that was evidenced at the Emirates on Wednesday in his willingness to take a pot-shot such as that.
Before that, though, Walcott was the outlet to so frequently get behind the Ludogorets defence. He looks undroppable right now -- though you could say that about a few Arsenal players.
