The Southampton and West Ham comebacks were pretty different IMO.
Against Southampton we were unlucky to be 2 down. We created good chances that we didn't put away and could have been level at least. Against West Ham we looked utterly clueless in the first half, I think the xG was over 2 for WH, and 0.07 for us. I'm going to bet that Liverpool's comebacks were closer to the Southampton game than the West Ham. Of course, we won, which was entertaining and I'm happy to see.
Take the CL, we beat PSG away and lost at home, but put in a good performance against a strong team. On another day Cavani's chip goes in, or Martial doesn't miss the rebound and another open goal. But we stupidly lost to Istanbul, who have lost their other 4 games in the group. We looked drunk in that game. We beat last season's semi-finalists 5-0, then days later were very poor against relegation level trash like Arsenal & West Brom. That's why we're seen as inconsistent.
I agree a lot with
@TheRedDevil'sAdvocate , in that pointing this out doesn't mean people are OleOuters or anything like that. Just that we need to stop being as bad as we were against Arsenal/Istanbul away.
