An early James Milner penalty proved to be the difference between the two sides as Liverpool created chances but couldn't put their Bundesliga opponents to bed, which created something of a nervy finish at Anfield.
In his Liverpool Echo column, Molby wrote: "If you're looking at the positives, we kept a clean sheet and managed to get off to a really fast start – but it remains a worry how many chances we need to score at Anfield.
"All of our best performances have been away from home, as well. Is that because of the expectation?
"What has made a difference is the fact Liverpool rarely hold comfortable leads at home. They've not been clear in games often – when you get that cushion, it's so much easier to play.
"We had enough chances to give that cushion to express ourselves, though. The amount of chances we missed is a problem and we won't get as many as that on Sunday.
"That being said, this was the sort of game you expect three days before a cup final. Get the job done, avoid any major injuries and start preparing for the big game on Sunday."
It certainly may not have been pretty but as Molby said: job done. With that, there is probably a little bit of momentum behind Liverpool having won one of their bigger games of the season to keep their hopes of winning the Europa League alive - and with that a place in next season's Champions League.
Three clean sheets from their last three games will give the defence some confidence as they have been frail again at times this season. Molby outlined that it was the kind of game you'd expect immediately before the final, so the result being the main thing, a performance in this case is secondary.
The quick start certainly gave Liverpool that platform to create chances, but the lack of ruthless streak is a little worrying, though we have seen it in spells this season, and the Reds will hope it arrives again when they face Manchester City at Wembley on Sunday, as they aim to lift the League Cup for a ninth time.
