If we are not counting Sol, then I would say the only better CB than Kos in that time is Kolo...also assume we are not talking about Adams and Keown at their best here.
If we are just talking Emirates era, then I would say he was the best...though if someone said Per was the better, then I wouldn't argue too much, as he is a close second for me.
Not been a great collection for us since the stadium move though...
Gallas was very good, but caused a lot of **** here...Djourou I quite liked, but despite having everything you wanted in a CB for a Wenger team, he didn't have the mental attributes to put it together...Verm, good but a little overrated...Luiz, far too inconsistent.
Gabriel and White are up there, tbh...but the fact 2 very recent players are high up the list, shows that CBs at the Emirates haven't been that great on a consistency level.
You forgot the "best" quartet of defenders.
All played in Champions League
