Holding played left side next to Ben White in the Carabao Cup even with Kolasinac available.
Saliba broke through at Saint Etienne playing left centreback. Not only is he quite two-footed, but like lots of ball-playing defenders, playing on the left side opens up the centre of the pitch for him - I actually prefer him there. Similar to when you watch van Dijk spray the ball around from that side.
I think it's just common sense from Arteta. You put a very one-footed player on the wrong side and it's not going to go very well. Most of our defenders could barely pass with their 'strong' foot. And the one that could pass with both, David Luiz, played on the left all the time over Pablo Mari and Kolasinac. Fans have
taken the general idea further than needs be.
