I meant that we should have been getting better than Koscielny, Luiz isn't even better than a finished Koscielny. We were much better defensively at times last season than at any time this season. People saying they're satisfied with Luiz indicates they're happy with the downgrade when we should be aiming to upgrade. He's not been fine, none of the evidence suggests he's been fine. His good performance have been few and far between. Not sure how he's done as well as Koscielny when Koscielny helped us in big victories over United, Chelsea, Napoli, Valencia and was excellent vs Sp**s at Wembley. Luiz has had one top big game vs United, that's it.
