No it isn't. We were conceding in preseason and the early games with Allison, it's probably more down to early season and getting up to speed fitness wise after such a hectic season, it's hard to maintain that level of energy, pressing and concentration for long periods of time. We're still defensively very good in most basic ways, we're organised, we have players who commit to throwing their bodies on the lines to prevent a chance and we're generally a hardworking team.
Aside from the odd gaff early on, Adrian has been a good stand in, us conceding more is nothing to do with the goalkeeping situation.
I think we'd have conceded less with Alisson in goal for the simple reason that he's a much better goalkeeper
