An under-cooked Reds outfit were beaten 4-0 by Man City on Thursday night, starting well but becoming increasingly lethargic as the minutes drifted by.
It wasn’t a complete shock, considering they had celebrated their Premier League triumph days earlier, so an overreaction was uncalled for.
A response will be demanded by Klopp on Sunday, however, as struggling Villa look to spring a surprise at Anfield.
Joel Matip is still the only player unavailable this weekend, having picked up a foot injury that is likely to rule him out for the rest of the season.
Everybody else is in contention to start, which is an enviable position to be in for Klopp.
Liverpool’s XI vs. Villa
It’s difficult second-guessing Klopp for this game, considering the options at his disposal and the potential for rotation.
The boss could easily field the same XI that lost to City, in theory, but that would be a surprise.
Andy Robertson was horribly out-of-sorts against City, meaning Milner could be drafted in at left-back.
With Fabinho anchoring the midfield, Keita and Oxlade-Chamberlain would bring an exciting, attacking look to the middle of the park.
If Klopp really wants to ring the changes, there are plenty of other alterations that he could make.
In his pre-match press conference, Klopp said that he won’t “give Premier League games as Christmas presents”, indicating that youngsters may struggle for minutes.
Should Robertson be retained, Milner could push into his preferred midfield role, deputising for either Henderson or Wijnaldum.
Oxlade-Chamberlain’s versatility means Klopp may consider using him on the right-wing – a position he admittedly struggled to impress in at Everton last month.
It feels highly unlikely, though.
Alisson; Williams, Gomez, Van Dijk, Robertson; Henderson, Milner, Keita; Oxlade-Chamberlain, Minamino, Origi.
It would come as a shock to see Klopp make huge changes, but this is a perfect time to rotate his squad and several alterations are to be expected.
Whatever Liverpool’s lineup is, they should have enough to get past a limited Villa team, returning to winning ways in the process.
Klopp will not be amused after Thursday night and Villa may be on the receiving end of his chagrin.
