Arteta has declared he is now ready to change his goalkeeper during a game if he feels it will change the course of the game.
Leno, a former Arsenal goalkeeper, told The Times: "I would feel very strange and very surprised if I would see the No 17 was coming off in minute 75.
"Everyone in the stadium would be surprised. It doesn't matter if it's myself or Alisson at Liverpool, it doesn't make sense.
"The keeper coming on would feel even worse than me, coming on and not warmed up with no contact with the ball and no feeling for the distances. If the manager asks me, I would say, 'Don't do that'."
