Diego Simeone remains a favourite of the Atletico Madrid board.
Quique Flores, who was appointed last week following the sacking of Abel Resino, has only signed a deal to the end of this season.
Madrid sources say Atletico's long-term plan is to have Simeone installed as coach for season 2010/11. The Argentine is currently in charge of San Lorenzo and admits he has ambitions of coaching in Europe.
