Manchester City striker Carlos Tevez says he is tired of too much football and may consider quitting if Argentina win the World Cup next year.
Tevez, 25, moved from Manchester United to City in the summer but has struggled to break into Argentina's first XI.
"It crosses my mind to hang up my boots if we win the World Cup," he said.
"It's complicated, there's my family, the desire to return to Boca Juniors. I'm keen to get a bit of calm. I've won a lot. Football has saturated me."
Tevez began his career in the Boca Juniors youth team in 2001, moved to Corinthians for a season and then headed to England for spells with West Ham and Manchester United, where he won two Premier League titles and the 2008 Champions League.
He joined Manchester City in July and is contracted to stay at Eastlands until 2014.
"I'm a little tired of so much football, so much football...I want to enjoy my family a bit," said the talismanic forward, who was speaking to Argentine newspaper Ole ahead of the weekend friendly with Spain in Madrid.
Although Argentina eventually scraped through the World Cup qualification process, Tevez has struggled to cement his place in the starting line-up under the guidance of boss Diego Maradona.

But after admitting he had so far under-performed for his country, he expressed his desire to make his mark on the South African stage next summer.
"Nobody likes to be a substitute," Tevez added. "It doesn't worry me to sit on the bench and I will support my team-mates.
"I'm not going to sit with my arms folded and watch the World Cup pass by. No, I want to play, I want to enjoy it, I want to be there and I'm going to try 10 times harder than before.
"I'm determined to turn this situation around. At the World Cup they are going to see the best Carlitos Tevez."
Argentina secured their spot at the 2010 World Cup after a late Mario Bolatti goal in a nervous 1-0 win in Uruguay last month.
