Jamie Redknapp has claimed that he has been “blown away” by the Liverpool revival engineered by Jurgen Klopp.

The Merseysiders thrashed Southampton 6-1 at St Mary’s Stadium on Wednesday night to roar into the League Cup semi-finals.

It was Liverpool’s fourth consecutive away victory, following emphatic Premier League wins at Chelsea and Manchester City, as well as a Europa League triumph at Rubin Kazan.

“He has got the whole club buzzing. He seems to have a magic wand, Jurgen Klopp, and has sprinkled magic dust on everyone.”, Redknapp told Sky Sports on Wednesday night. “They all look like completely different players.

“To come here and produce that kind of performance is incredible. They were playing against a very good Southampton side. No Coutinho, no [Roberto] Firmino. They have scored 13 goals in three games against Chelsea, Manchester City and Southampton. There is an energy about them.

“At the moment there is no limit to what they can do. I have been blown away by what he (Klopp) has achieved so far. It has been absolutely brilliant to watch.”

Liverpool went a goal down to a Sadio Mane strike after 39 seconds but Daniel Sturridge responded with two outstanding strikes in the first half, before a Divock Origi hat-trick and a goal by substitute Jordan Ibe put a gloss on another sensational away performance from Klopp’s side.

Redknapp added: “It’s the options he has now. He’s not played Coutinho or Firmino tonight, [Christian] Benteke’s on the bench, he’s got Sturridge back. I still think Sturridge is the best centre-forward they’ve got. Aguero is the only one better in the Premier League.

“If you look at the other players, Lallana was exceptional tonight, Joe Allen came in and did a job, Emre Can. Ibe has got real pace. Origi has now got a hat-trick. What is that going to do for his confidence?”

Southampton legend Matt Le Tissier was also impressed by how well the visitors had dismantled Koeman’s team.

“If I was a Liverpool fan tonight I would be very excited  about the rest of the season because that was incredibly impressive,” Le Tissier told Sky Sports afterwards.

Liverpool, who have climbed to sixth in the Premier League table, travel to struggling Newcastle on Sunday looking for their fifth consecutive away win.
