Liverpool boss Jurgen Klopp told what to do to stay ahead of Premier League rivals

• Liverpool have not invested in their playing squad over the last two windows.

• The Anfield club have been linked with a move for Red Bull Leipzig striker Timo Werner.

Jamie Carragher reckons his former side need to "spend big" in the next transfer window if they plan to stay ahead of other clubs in the Premier League. Ex-England international, now Sky Sports pundit Carragher insists Jurgen Klopp's team need strengthening into two major positions; in the final third and the left-back position. Speaking on Sky Sports' The Football Show, Carragher said: "If you look at the XI, I think it's very difficult to improve that. "I actually felt Liverpool did need reinforcements [in the last two transfer windows]. I just feel this team has been together now for 3 or 4 years.

That doesn't mean it should change but I just think there should be something more certainly in reserve for the front three. "I think Liverpool have been lucky that the best players have never really suffered injury-wise. When you think of the big players, the front three, the two full-backs, and Virgil van Dijk. "I just think can there be more competition, certainly with [Andy] Robertson at left-back. He's the only recognised left-back at the club.

"I think Liverpool need more than Divock Origi to back-up one of the front three when they're out. Hence why Liverpool have been linked with Timo Werner. I actually think Liverpool do need to invest to keep them where they are." The Reds legend Carragher continued: "For me, a strong understudy to Andy Robertson and I wouldn't say a big-name striker, but certainly someone whose really going to push that front three. "Because that front three are all getting to that age, 28, 29, 30. An attacking player is not someone who goes to 33, 34 normally.

"I think they need to spend big and keep themselves ahead of the pack."
