However, Totti who played alongside the Egypt worldwide during his final two seasons of his 25-year stint with the Giallorossi, claims the 25-year-old could still develop to another level, despite labelling as one of the world's best footballers.
Salah has so far registered 30 goals and 10 assists in 36 games for Liverpool, good for a goal involvement every 72 minutes.
"I know him well, he is a good friend and wants to keep improving, to keep getting better as a player".
His stunning goal scoring rate under Jurgen Klopp's management has got clubs from all over Europe going head over heels for the Egyptian, as reports from Spanish portal Gol Digital claims that Bayern Munich has joined the race with Real Madrid to snatch the signing of this season's sensation in next summer's transfer window.
"The coaches help me so much to do that and I also work hard alone after the training sessions".
And the Roma legend thinks the Egyptian frontman could lead the Reds to their sixth European Cup win.
The Liverpool Echo reports that Klopp is desperate to tie the winger down to a new deal as the 25-year-old now has a contract at Anfield Stadium running until 2021.
"Salah is not a centre-forward, I don't think he is a player who can score goals consistently over a period of time".
"I don't want to say too much because we still have a long way to go in the season and I don't want to give too much away".
Salah will be looking to continue in his goalscoring ways as Liverpool take on West Ham tomorrow at Anfield.
