I mean, this is just about who the strongest we have is, as opposed to the strongest right now. And as a wing back, Pawel definitely, because perch could even play the position baptiste does and rotate out to a full back spot.
I could do a full write up about the formation because it's a very smart one, but to put it simply, on the attack, our wing back becomes a winger and out wide centre back becomes a full back to support them (it's why Baptiste is always at the edge of the box alongside Pawel). When defending, we revert back with the wide centre back helping stop the cross with the wing-back. So we end up being a 4atb when we're attacking and a 5atb when defending.
