Reds forward Salah won a penalty from which he drew Liverpool level against the Hammers after going down under the challenge of Arthur Masuaku.
Liverpool went on to win the match 2-1 as Diogo Jota continued his fine form with a late winner from Xherdan Shaqiri’s defence-splitting pass.
The Anfield fixture was played the day after the death of Nobby Stiles, and Cascarino believes Liverpool’s victory was tainted by Salah’s “cheating” in light of the World Cup winner’s passing.
“In the week when we lost Nobby Stiles, to see a player do what Salah did makes me think that the game as it was played by the England team of 1966 will be gone completely within the next 10 years.

“Imagine showing that generation an example of what they would have considered cheating being rewarded in that way.
“The culture started to change during my playing career and now when I watch kids football they are all as good at diving as they are at everything else.
“And when I say good at it, I mean they go down in a way that may deceive a referee into giving a free kick.”
While Cascarino acknowledged West Ham full-back Masuaku made contact with Salah, he insisted there was “nowhere near enough to knock him off his stride”.
Salah, 28, has enjoyed a fine start to the season and his penalty against West Ham took his tally to seven goals in seven Premier League games.
