Liverpool seriously pulled it out the bag when they signed Mohamed Salah this summer. 

It's easy to forget just how much skepticism surrounded the deal and with good reason, too. Salah had previously spent time with Chelsea between 2014 and 2016 with many drawing the conclusion that he simply wasn't cut out for the Premier League.

Nevertheless, the Egyptian's renaissance with AS Roma was enough to persuade Jurgen Klopp that he would take his second chance in England and for just £38.5 million, he was bang on the money.

With 29 goals and seven assists in just 29 appearances in the famous red jersey, it has left Chelsea fans scratching their heads as to what went wrong for the winger just two years earlier.

Numerous pundits and players have tried to trace the cause of the disparity with Eden Hazard and Frank Lampard leading the way. 

Frank Lampard and Eden Hazard's guesses

Hazard speculated earlier this season:  “He is still my friend and we are still in contact. He’s a top, top, top player. He did not get his chance at Chelsea -- maybe because of the manager, because of the other players? I don’t know.

"He has quality but in that period I remember we had me, Willian, Oscar, so for him it was not easy."

It was a theory corroborated by current BT Sport pundit Lampard, who noted: "It wasn’t easy and he was up against the likes of [Eden] Hazard, Oscar and [Juan] Mata was around there in his early day."

Further down the line and the two club favourites have been proven right with Salah himself speaking out on the issue in an interview with Marca. It seems that now, beyond doubt, the lack of game-time given to him by Jose Mourinho was the recipe for failure.

Mohamed Salah proves them right

When asked about his doomed spell in west London, he explained: "I didn't do well because I didn't play many games. I was there for one year, but I only played during the first six months. After that, I hardly participated.

"I went to Fiorentina, scored goals, then in Rome I played very well and returned to England. But it's not a matter of succeeding or not..."

We're all looking at you, Jose.

Given the career paths of Romelu Lukaku and Kevin de Bruyne since leaving Chelsea, too, their treatment of Salah appears another lapse in judgement.

Salah didn't exactly light up the Premier League when he was given the chance but the Egyptian's current form tells Chelsea all they need to know.
