Only thing I’ll say is that quality depth only really works when you’re winning stuff and paying well.This is competition, good players should thrive on that.
KT and Zinchenko have both played well when given the opportunity. Tomi ( who I don't think will be playing LB too frequently) had a great game.
Compete with each other and improve if you want the starting spot. Also all these guys are fairly injury prone. There's going to be game time there for all of them.
I think as Arsenal fans we've become so used to a lack of depth that we overly worry about stuff like game time for individuals when they have some competition.
