Salah left Chelsea for Fiorentina in January in a deal worth £26.8 million and involved Juan Cuadrado who went the other way.
Salah scored the second goal in the Italian side’s 2-0 win over Spurs which knocked them out of the Europa League on Thursday evening.
Montella claims that Cuadrado and Salah have similar qualities.
“Salah is a player that, even if he takes some breaks, is devastating over 40 or 50 yards,” he said.
“Who did better out of the Cuadrado exchange? Fiorentina earned a lot of money and, on the pitch, they are similar players.”
Fiorentina now have to focus on their away trip to the San Siro to play Inter Milan in order to help secure qualification for next season’s Champions League.
Montella added: “We are satisfied, great credit is due to the players and to all the fans. There’s little time to enjoy it, though, as on Sunday we have a very important match.
“Inter are certainly going through a really good spell in which they have rediscovered their confidence and self-esteem.”
