The ex-Liverpool head coach is taking some time away from the touchline but it is understood that two managerial positions have captured his attention.
Klopp stepped down as Liverpool boss at the end of last season after a hugely successful nine-year spell which included Premier League, Champions League and domestic cup success.
According to UOL, the 57-year-old is becoming 'increasingly worn out', and his dissatisfaction has become a 'recurring theme in the corridors' as time has progressed.
The report adds that people close to the German have been told that he would only leave Red Bull to take charge of Real Madrid or Brazil.
Those two possible destinations are interlinked, as current Real boss Carlo Ancelotti is on the Brazilian FA's list of candidates to take over from the recently-sacked Dorival Junior.
Ancelotti taking the job would therefore open up a vacancy in Madrid which Klopp could be a prime contender to fill.
Reports indicate that the Brazilian FA have not approached Klopp about taking charge of the national team, and it is unclear whether Los Blancos have reached out.
If any club or national team manages to tempt Klopp away from Red Bull, they will need deep pockets.
I can talk to Jurgen, I've experienced it."
