Luiz Felipe Scolari has been linked with taking over Beşiktaş and Fenerbahçe according to Fanatik.
Fenerbahçe boss Ismail Kartal is expected to leave at the end of the season and Beşiktaş manager Slaven Bilic’s future remains uncertain.
The Yellow Canaries are still in the title race and the Turkish Cup semi-finals.
Scolari resigned from his position as manager of Gremio on Tuesday after just two weeks in charge of the Brazilian side.
The 66-year-old coach took over the Porto-Allegre based club just a mont after resigning from the Brazil national team following a disastrous World Cup culminating in a humiliating 7-1 defeat against the eventual champions Germany.
Gremio chairman Romildo Bolzan confirmed the news on the official club website: “He asked to resign this morning and I understood his cycle and capacity to take the club on had come to an end.”
The Brazilian giants finished last season in seventh place and missed out on Copa Libertadores qualification to rivals Internacional a fortnight ago.
Scolari won the World Cup as manager of Brazil in 2002 and has manager Premier League giants Chelsea in the past.
