Now just imagine that those 9 assists came from one individual and then imagine we had 2 individuals on both flanks producing 9 assists, our attack would become super hot.Zinchencko, Delph and Mendy combined for 9 assists, 2 short of Pool's LB. So we are already close on the Left. It's the Right that needs work. Granted Pool's RB also takes cornerkicks so he has an added advantage.
This is not to downplay the role of Zinny and Walker. I for one never thought Zinny would ever become a regular at LB for us but he has shown he can do it. But I recognize that there is room for improvement in that department in our squad.
There is hardly any defender in our squad that is good on the ball like Zinny and our defensive solidity inspite of our insane highline (think we've only shipped 22 goals in the PL all season) has a lot to do with Walker. However dominating the flanks defensively and offensively whilst putting in delicious crosses for attackers is not really their forte.
