In terms of football punditry, the views of very few men in the sector are trusted by all.

The likes of Paul Merson, Charlie Nicholas, Garth Crooks and Tony Cascarino spout so much nonsense that it often leaves regular fans thinking they could do a better job in the studio.

However, there are some who speak a lot of sense and former Liverpool defender Jamie Carragher is certainly one of those.

The Sky Sports regular is a great analyst of the game, with he and Gary Neville doing a great job on the Monday Night Football.

Carragher now has a regular gig writing for The Telegraph and some of his columns have made for very interesting reading.

WHO IS THE PL'S BEST SIGNING

One topic he chose to take on this week was which Premier League signing has had the biggest impact so far in England's top-flight?

To be fair, there are a hell of a lot to choose from, with Romelu Lukaku, Alvaro Morata, Alexandre Lacazette and Davinson Sanchez all hitting the ground running.

Even Arsenal's Sead Kolasinac has been outstanding at left-back, but Carragher has chosen a different player; Liverpool's Mohamed Salah.

SALAH THE STANDOUT PURCHASE

He writes: "Of all the transfers last summer, none has had more impact than Liverpool’s Mohamed Salah.

"Romelu Lukaku has also made an immediate impression at Manchester United – who have made a better start to this season - but Salah has only one goal fewer than the centre-forward. It is some goal rate.

"Since Luis Suarez was sold to Barcelona in 2015, the most goals any Liverpool player has scored in a season is 14 (Philippe Coutinho in 2016/17).

"Salah scored his 10th of the current campaign in midweek. When I saw Salah score his first for the club at Watford on the opening day, I felt this was a player who would score 15 this season. I underestimated. He is on schedule to get 25."

LIVERPOOL'S MAIN MAN

It's hard to disagree really, with Salah really taking on the responsibility of the likes of Coutinho and Sadio Mane during their absences this season.

Without him, Jurgen Klopp's side would have struggled far more.

CARRAGHER PRAISES LIVERPOOL FOR GAMBING

He also says: "There has been plenty of criticism of Liverpool’s recruitment in recent years – much of it deserved. But just as with the signing of Sadio Mané in 2016, they have spent very well in bringing Salah back to England after his disappointing spell at Chelsea.

"Paying over £35 million seemed risky, but as was the case with Mané, Salah already looks to be worth more than he cost."

Sometimes, it pays off to gamble.
