The Egypt international moved to Liverpool FC in a £39m deal from Serie A giants AS Roma in the 2017 summer transfer window.
Liverpool FC faced interest from FC Barcelona in Coutinho last summer but the Reds managed to keep the Brazil international for another four months.
Salah made an impressive start to the season alongside Liverpool FC trio Coutinho, Roberto Firmino and Sadio Mane.
However, Coutinho finally completed a switch to Liverpool FC in an £142m deal from FC Barcelona in the January transfer window.
Salah has excelled since Coutinho’s departure and the Egypt international has scored 29 times in 31 games in the Premier League this term.
The African forward has also netted nine goals in 11 outings in the Champions League to help the Reds reach the semi-finals.
Former Liverpool FC star Murphy believes Salah has grown in stature at Liverpool FC since Coutinho’s exit.
“As the season has gone on he has got even better and you have to factor in that he has done that despite Liverpool losing Philippe Coutinho, who was so pivotal to their creativity, to Barcelona. Salah has actually taken on more responsibility since then,” Murphy told BBC Sport.
Liverpool FC will take on Italian giants AS Roma in the Champions League round of four later this month.
The Reds are in third place in the Premier League table but four points behind Manchester United.
