The Egypt international completed a £39m move to Liverpool FC from Serie A giants AS Roma in the 2017 summer transfer window.
Salah’s move was met with some initial skepticism given his struggles at Chelsea FC during an eight-month stint in 2014.
However, the African forward has scored a staggering 29 goals in 31 games in the Premier League this season.
Salah is sitting four goals clear of Tottenham Hotspur striker Harry Kane, who is his closest rival for the golden boot.
Liverpool FC are in the Champions League quarter-finals thanks in part to Salah’s eight goals in nine outings.
Former Chelsea FC striker Sutton is in no doubt that Salah is deserving of the PFA player of the year award.
“The impact he has had on the Liverpool team…” Sutton told BBC Radio 5 Live.
“He was £38m. He has been the best signing. He has been the best player.
“Salah has come from nowhere. He has exploded. He just keeps going. For the volume of goals. He is a wide player. It has to be Salah.”
Manchester City midfielder Kevin De Bruyne is thought to be Salah’s closest challenge for the PFA award.
Salah netted four times in Liverpool FC’s resounding 5-0 win over Watford, before scoring the winner against Crystal Palace on Saturday.
