Really good signing. Left footed, good passer, strong and aggressive. Be interesting to see if we go straight to a back four with Saliba and Gabby or wether Arteta starts with a 3-4-3 and pairs Saliba/Gabby over time.
Reckon Luiz will be paired with Gabby initially, with Saliba coming in. Also potential to play all three in a 3-4-3
That would be sensible - also some rumours claiming we'll stick to 3-4-3 until Mikel lands his midfield targets. Charles Watts saying Arteta wants a 4-3-3 with the personnel to switch into a 3-4-3. Saliba looks class though - he's a proper talent. Not to bash Chambers, Holding etc.. but he seems to be a completely different level
Which is exactly what we need. Chambers and Holding are decent enough, but not at the required level for Arsenal to be pushing for Champions League spot.
