Petkovic linked with Sunderland as Poyet replacement
Gus Poyet's status at Sunderland is in doubt, according to Italian sources.
TMW says Poyet could be sacked in days, with Sunderland sounding out potential replacements.
Sunderland have asked the Swiss FA about Vladimir Petkovic 50, taking charge on a caretaker basis to the end of the season.
Former Schalke 04 boss Ralf Ragnick is also under consideration.
