Manchester City are reportedly keeping tabs on Mauricio Pochettino and Julian Nagelsmann as fears grow over Pep Guardiola's future at the Etihad Stadium.
The Catalan coach is out of contract at the end of the campaign and recently revealed that talks over a new deal have yet to begin.
Guardiola has also previously hinted that he is not interested in a return to Barcelona and wants to stay on at City, but Goal reports that he is no closer to formally committing.
City chiefs are said to have drawn up a shortlist of potential successors, with RB Leipzig's Nagelsmann and out-of-work boss Pochettino among those being considered.
Nagelsmann guided Leipzig to third place in the Bundesliga and to the semi-finals of the Champions League last season, while Pochettino has been without a job since departing Tottenham Hotspur 12 months ago.
