Carlos Tevez admits he is "physically exhausted" after a tremendous season with Manchester United.
The Argentina striker has played 47 games for United since joining from West Ham in August, netting 19 goals as he helped fire the team to the brink of a league and Champions League double.
However, Tevez admits his tiredness could see him sit out his side's World Cup qualifier against old enemies Brazil, on June 18.
"After the Champions League final, I will need some weeks to rest," Tevez told Argentinian newspaper Clarin.
"After the Copa America in Venezuela (last year), I came to Manchester United and haven't stopped playing. I'm physically exhausted.
"I will talk to Coco (Argentina coach Alfio Basile) to see if it is for the best that I join the national team."
First Tevez has the Champions League final to think about as United take on Chelsea on Wednesday, looking to add that trophy to the Barclays Premier League title they lifted a week ago.
The former Boca Juniors and Corinthians star was delighted to get his hands on a trophy once again and has vowed to do everything possible to ensure it is United who return from Moscow victorious.
"I celebrated so much last week because it's been a while since I celebrated a title," added Tevez. "I was already losing the habit which I loved.
"I hadn't been a champion since 2005, when I lifted the Brazilian title with Corinthians.
"Moreover, it's my first title in Europe and that doesn't happen every day.
"I called my uncle, who suffers from cancer, from the stadium. He was very emotional, as was I obviously.
"I know that these are little moments of happiness that are very good for him and that gives me the strength to continue.
"I promised him that we will do everything to win the Champions League.
"Chelsea have a great team, they attack a lot and have a lot of players who head very well, but we have our skills too."
Tevez also has his sights firmly set on winning an international title with Argentina, especially after losing the last two Copa America finals to Brazil, in 2004 and 2007.
"It would be wonderful," he said.
"Among all the dreams I have, winning a title with the national team is the biggest in my mind.
"I give my all for every shirt but the blue and white (of Argentina) is the most dear to me.
"I have been fortunate, I have celebrated titles with Boca, Corinthians and now Manchester. What is still missing is one with the national team."
