Salah recalled a conversation he had with Wenger, in which he sought to understand the difference between good players and truly great ones.
"I think I got that advice from Arsene Wenger in the past," he said in an interview with TNT Sports expert Steve McManaman.
"He told me: 'The great players, it does not matter how he performs in the game. He always stays focused and waits for the moment. He's always in the game'. And I put that into consideration a few years ago.
"Players' emotions go up and down, [but] I don't want my emotions to be like this. I just try to be stable and understand that not every game you're going to have your best game. If you stay focussed, maybe you will have one chance."
