The charismatic German chief splashed the cash in the summer.

But despite coughing up for fresh attacking talent, Klopp missed out on his top defensive target Virgil van Dijk.

Liverpool could only manage a 1-1 draw with Spartak Moscow last week in the Champions League.

They also recorded a 1-1 stalemate with Newcastle at St James’ Park yesterday.

Collymore, who played 64 games for the Anfield heavyweights, says Klopp might as well put his faith in youth.

He wrote in The People: “Somewhere in the club, there must be a young centre-back who deserves his chance.

“Jamie Carragher is the classic example, if you are willing to trust a youngster.

“Carra came in when Neil Ruddock was not doing the business, when Mark Wright was not doing the business, he was brought in as a right-back and ended up a club legend in central defence.

“Jurgen Klopp needs to go and look a bit deeper at what is available - maybe knock on Steven Gerrard's door, and see if he has the central equivalent of a Trent Alexander-Arnold.

“The fans would buy into a young centre-back being given a chance at this stage.”

Liverpool will face Manchester United after the international break.

They currently sit seventh in the Premier League, seven points off pace setters Manchester City.
