Lallana is expected to be out for a month, having suffered the injury during the closing stages of England’s 2-0 victory over Lithuania at Wembley last Sunday.
The former Southampton midfielder been one of the most reliable performers this season in a Liverpool side who have lacked consistency, and his absence will be felt keenly as Reds boss Klopp attempts to secure a top-four Premier League finish.
They sit fourth going into the weekend’s fixtures, with a four-point advantage over Manchester United in fifth.
United do have two games in hand, but that is no guarantee that they will make up the gap, as they have matches at Manchester City, Arsenal and Tottenham before the end of the season.
Liverpool’s form going into the international break was encouraging; home wins over Arsenal and Burnley were followed by a draw at Manchester City, and they will start favourites against Everton, who have not won at Anfield since September 1999.
Sadio Mane’s goal in the seventh minute of stoppage time gave Klopp’s team a 1-0 victory in the reverse fixture at Goodison Park in December, and a win on Saturday would secure a first league double over their local rivals since 2011-12.
Liverpool will be helped by the likely return of Jordan Henderson after more than a month out with a foot injury, with the England midfielder having resumed full training during the international break.
Klopp is in no doubt that Champions League qualification is in Liverpool’s hands.
«In this moment, we should only think about how we can do it,» he said.
«Would it be a disappointment if we don’t reach it? Yes because we think we should qualify for it.
«Is it possible that we don’t qualify? Yes because of the league, because of the opponents and all that stuff.
«But it is our big target, of course. We want to do everything to get it.»
