Thatâ€™s the view of Manchester United legend and BT Sport pundit Rio Ferdinand.
Liverpool talisman Salah has been sensational for the Reds following his move from Roma last summer.
The Egypt international has netted a staggering 39 goals in all competitions under Jurgen Klopp this time out.
Salah, 25, has been compared to Real star Ronaldo and Barcelonaâ€™s Lionel Messi this season after his breakout year.
However, Ferdinand says the Anfield winger must impress for the next 15 seasons to be considered in the same bracket as Ronaldo.
â€śHeâ€™s doing alright! Heâ€™s hitting the numbers,â€ť Ferdinand said of Ronaldo on BT Sport.
â€śHeâ€™s going to have to do that for the next 15 seasons to get to that manâ€™s mark where he is nowâ€ť
â€śTo put it into perspective, Mo Salah is being spoken about and rightly so as having an unbelievable season.
â€śHeâ€™s going to have to do that for the next 15 seasons to get to that manâ€™s mark where he is now. Itâ€™s crazy.â€ť
Ronaldo netted a late penalty against Juventus tonight to send Real into the Champions League semi-finals.
Salah and Liverpool are back in action on Saturday evening when the Reds host Bournemouth in the Premier League (5:30pm kick-off).
Kloppâ€™s men come into the clash on the back of their Champions League heroics against Manchester City last night.
