Coppell took the Royals into the top flight for the first time two seasons ago, but has become disillusioned with life in the hot seat, and reckons he has taken the Berkshire side as far as he can.
"I'm looking very shortly at having some time off," the 52-year-old told The Sun.
"My first stint at Crystal Palace was nine years, bits here and there, and then Brentford, Brighton, and four years here. I am probably due a break.
"I'd do what Paul Jewell has done, play a bit of golf, get out of the environment a bit, and then try to re-educate. I'd love to go and watch all the top managers here and abroad.
"I can't enjoy management. I work all week to win a game. If we win I have an unbeatable high for 20 minutes, but then it's thinking about the next game.
"If we are beaten, it's a bottomless pit. It goes through my mind when I get beat, do I need this?"
