We conceded 2 goals over two games. Hardly a crisis. Creating and taking opportunities was very much the problem.
Why are you only using this semi-final as your universe? We played two, lost two, conceded twice, and scored none.
That's poor enough, however in the wider context of one win in seven games (and that against a League 2 side) and some abject displays, there's obvious cause for concern
And the fundamental issue, and one that has been apparent since Klopp joined, and before that too, which he has shown no sign of being able to fix, is that we have the worst defence of any Top 8 side in the league.
