Some of the current criticism reminds me of massive overreactions earlier in the season whenever somebody went past Trent. Compare that to when Virgil fucks up and we just wave it away like nothing happened. Defenders are going to make mistakes from time to time. That's why it is a team sport. Yes, Joe had a few iffy moments tonight but that can happen to anybody. No need to go overboard with the criticism.
Having said that, I do wonder if, personality-wise, he is the sort who gets nervous or worried when there is competition lurking in the background, breathing down his neck sort of thing. In Klopp's post-match interview with LFCTV he seemed super excited that Joel was coming back into training. Just wondering what effect that can have on a player who hasn't solidified his ownership of the shirt as yet.
