Not sure I agree wholly. I think that Zinchenko offers passing options that a more traditional LB simply doesn't provide. He takes risks that can expose us yes - but by the same token we are not the same going forwards without him. This for me is the dichotomy with Arteta's current team in general - the fine balance between attack and defence sometimes goes wrong. And here is where I feel we need to find more ruthlessness in finishing chances. It certainly seems as though we create many goal scoring chances but are not efficient in putting them away. A proper no 9 might solve this?
