Manchester City ace Carlos Tevez admits he lacks motivation and has considered retirement.
The 26-year-old has four years left on his Eastlands deal, but being separated from his daughters has been difficult to take.
"For the last year I haven't lived with my daughters, they are growing up and I'm getting worn down.
"After returning from South Africa I thought about quitting football, but I have a large family and now I have to continue.
"Football doesn't make me happy or as fulfilled as before. It becomes difficult to play like this," he said.
Tevez is struggling to get over the disappointment of Argentina crashing out of the World Cup to Germany in a humbling 4-0 quarter-final defeat.
"I was convinced (we would win),' he said. 'I dreamed about winning the World Cup up, getting back to Argentina with it, it's all I thought about. Losing hit me really badly. It's the hardest thing I've experienced in football.
"I have less and less will to carry on in Europe. I'll be here two or three more years and then I'll go back (home)."
