Look I’m not trying to make excuses for their unforced errors. I agree with everyone who says they’re not good enough for Arsenal. I would bin every last one of our current centrebacks if i had my way. I also agree with you that our defensive recruitment in recent times has let us down badly. The point I’m merely making here is that our defensive issues run far deeper than individual talent. Everyone’s raving about Saliba. I think he’d be making mistakes too if we had decided to keep him here this season. Put Van Dijk in our set up and I honestly think he doesn’t look as impressive in our team. A successful defensive unit is more about the system and organisation than personnel.
