Argentina head coach Alejandro Sabella says he will make a decision on his future over the weekend.
The 59-year-old guided the Albiceleste to their first World Cup final in 24 years in Brazil this summer, where they were beaten 1-0 by Germany after extra-time.
Sabella has now revealed he will consider his role with the side in the coming days and will only continue if he feels he can sustain his level of energy.
"First of all, I don't know what the idea of the AFA [Argentine Football Association] is about my future, and I have to rest a few days. I won’t hold things up much because I'm a responsible person. I'll think about it this weekend and I'll call [AFA president] Julio Grondona to meet him," he said to TV channels C5N and TyC Sports.
"I will only continue being the manager if I can give 100 per cent of my energy, as I ask of my players."
Sabella went on to praise the contribution of Lionel Messi at the World Cup, claiming the Golden Ball winner was selfless in his performances as he sought to get the best out of his team-mates.
"Messi is a good example of what the team has done. He thought plural and not singular, the team before him, to give before receiving," said Sabella.
"He made a huge sacrifice being the best player in the world. He's been a really important support for us to move past the first round, and he understood that in the other part of the tournament it was necessary to change our way of playing.
"We have to applaud him, we have to congratulate Messi because he sacrificed himself for the team. Thank you for being Argentine, thank you for choosing to play for Argentina and thank you for being always able to play."
Sabella added that he has yet to watch back the final defeat to Germany, brought about by Mario Gotze's 113th-minute volley, but admitted his side had the chances to win.
"I've not seen the match against Germany again. I want to rest. We could have won that match," he said.
"I congratulate Germany because they have been the best team."
