Palmeiras head coach Abel Ferreira admits he is considering his future in the role despite lifting the Copa Libertadores with Saturday's 2-1 final victory over Flamengo.
The 42-year-old Portuguese cited the hectic schedule for Palmeiras, juggling competing in Brazil's top flight along with continental competitions.
Palmeiras have played eight times this month and will back up from Saturday's final with a Brasileiro Serie A fixture against Cuiaba on Tuesday.
Ferreira, who became the first European head coach to win the Copa Libertadores twice, said the schedule was "insane" and "inhuman".
"The calendar is insane, it is inhuman," Ferreira said at the post-game news conference. "For me, I have to do a lot of thinking. The club has already demonstrated its will, I am very grateful to the club.
I can't manage with this rhythm of game, rest, game. This is not for me. I am not able to do it. I can't be at my maximum capacity, not at my maximum strength, not at my maximum energy.
"I always need to rely on the players. It's inhuman what they do here. If they want to grow, they gave to give up the round trips in cups.
"We have to have space to be able to rest and play well. I will stop, reflect and do what is best for Palmeiras."
Ferreira took over as Palmeiras boss in October 2020, having previously led PAOK and Sporting Braga.
