As many as 10 new players might have to arrive in the club's rebuild after the embarrassment of Manchester United's performance in their loss to the Reds.
Just six months after the Reds won at Old Trafford, United were beaten at Anfield.
The new manager will have to rip up the squad in the summer according to Rangnick.

It is embarrassing, it is disappointing, it is even humiliation.
If you want to have a chance against a team like this, you have to cause them problems and make use of those few counter-attacking moments ourselves.
The team needs a rebuild if you analyse it. Before you sign any new players, you need to know what kind of football the new manager wants to play and fit into that kind of profile.
While United are on course for their worst ever points total in the premier league era, they are still in the hunt for an unprecedented Quadruple having won the Carabao Cup and booked spots in the FA cup final and the semifinals.
With Manchester City due to play a game on Wednesday where they could regain the lead in the league, the Reds moved into first place.
They have better players than we have, and this was reflected by the result today. It is very embarrassing for us. They are better than us.
The visitors had made life easy for them in the match by giving up the ball in good positions, according to the scorer of the two goals.
They make our life easier in the middle of the park and in the back, they try to give us the ball in a one against one situation so it makes our life much easier.
We just want to score one goal and then we'll go for the second and third. It was a top performance from us. Hopefully we can carry on like this.
Bruno Fernandes agreed with his manager that the performance was not up to par.
The fans do not deserve us to play this way. They need more from us. They deserve more for staying and applauding us. The idea that the players were not trying was rejected by Fernandes, who said that we have to raise our level higher.
I think everyone runs. I think everyone is working hard. I don't think someone doesn't give 100%. We have to do it for everyone.
We have to say things but they are kept in the dressing room. We have to think of the next game now that it is over.
The difference between the two teams was obvious.
It is ready for the title. We are not. I don't need to say that the level is different. He said that we have to look at ourselves from top to bottom.
Having played a game more, United are three points behind fourth-spotted Spurs.
We are competing until the end. We have something to fight for.
