Ahead of Tuesday's clash, Klopp said: “Yes, it is right we didn't play well at Swansea but a few days before we played fantastic against Man City.
"It is how football is, how life is. Two weeks ago we had an 18-game unbeaten run and then you lose twice and everything feels different.
"We have to get immediately back on the winning track and we need results to reach our targets, we know that, but the solution is not out there in the transfer market in this moment."
However, during his pre-match press conference (below), Klopp suggested that the players who featured for the Reds at the weekend will be available.
“I'm not sure in the moment, it's really close. We have again a few knocks, different things, but nothing decided so far in this moment,” said the manager.
“It looks like all the players who were available for the last game are available again, but not 100 per cent.”
Huddersfield boss David Wagner, meanwhile, has an almost-fully fit squad to choose from, with only Elias Kachunga (knee) definitely out.
Danny Williams (hip) is a doubt, though, after he picked up a knock during the Terriers' 1-1 draw with Birmingham City at the weekend.
Wagner's side sit 14th in the Premier League, having failed to win any of their last six top-flight outings.
Klopp's pre-match conference
