Maybe - although there's an argument that he shouldn't even be in the team at the moment.
Yes, he's our best CB in terms of bringing the ball out, but I'd argue that he's probably our 4th best defender at the position right now. His play for the second goal on Wednesday was just bizarre - he's our CB, we're scrapping for the ball on the far left touchline, and he's pushing up ten yards into the opposition half and getting taken out of the play by the simplest of rolled passes, leaving them 3-on-2.
If we go to 3-5-2 (as we should) then I can see the argument for having Long in there; but if we stick with four at the back, I would rather see Findlay or Brown at LCB. We're in a scrap, and we've got to tighten up defensively.
