Manchester City's Argentine star midfielder, Carlos Tavez, says he could walk away from football at any time.
The City skipper says he is exhausted by the demands of the modern game and has revealed that he has considered walking away from the game altogether.
"I mean, look at all that running you have to do. Run, run, run.
"And you can't just run around at your own pace, you know. No - there's always someone else running, trying to get the ball before you. It's always the same.
"And kicking. You have to kick so much! What about the jumping - that's tiring too. Jump. Head. Run. Kick. It makes me sleepy justin thinking about it.
"I have to do it every week for Manchester City, then even when City aren't playing I have to go and do it all for Argentina.
"So tired. Sleep now."
