The Gunners saw three players booked for simulation in the 1-0 win against Huddersfield at the weekend.
In contrast, Salah netted a hat-trick for Liverpool in their 4-0 demolition of Bournemouth.
And for his second he rode a strong challenge from Steve Cook which saw him studded on the Achilles.
Arsenal legend Ian Wright believes the Gunners can learn a lot from Salah and his willingness to stay on his feet.
He said on Match of the Day: “When you look at that [on Granit Xhaka], there doesn’t seem to be a lot in that when you look at it again and then you see Salah stay up when getting wrenched down the back of his Achilles.
“You don’t want to see players getting suspended for those reasons.”
Arsenal boss Unai Emery also commented on the simulation of his players after the match.
He said: “I don’t want simulation for players.
“I want more rhythm in the match and the opposition can decide, when it has the ball, their rhythm and how they want to play, and it is a tough match for that, because the opposition stopped a lot in fouls.”
Emery reserved special praise for Lucas Torreira in the hard-fought win against Huddersfield.
“This is a very important result,” the former Sevilla manager explained.
“They stopped (for) about nine minutes this rhythm – a lot of cards, fouls and time lost and we needed patience and we needed to win by waiting for our moment.
“The first half we had chances and one goal maybe and the second half the same.
“Our goal is coming later, but is giving us the deserved result.
“Torreira has quality and his interpretation on the pitch tactically and in attacking and defensive moments, he is very fast in his mind and his ability and he can do very good work in defensive moments and he can get into the box and score.”
Arsenal return to Premier League action on Sunday when they take on Southampton (1.30pm).
