Jose Mourinho has refused to confirm whether he will remain at Fenerbahce at the end of the season following their 1-0 home defeat to Besiktas on Sunday.
The defeat leaves Fenerbahce eight points behind table-toppers Galatasaray with four matches to go.
The Portuguese manager joined the club at the beginning of last summer with the objectives of winning the league but they have lost out to rivals Galatasaray in the last two seasons.
The former Roma manager refused to commit his immediate future to the club.
Mourinho said: “I’m not speaking about next season. These are things to speak internally and not with the media. If there is something where I’ve been absolutely perfect is in my respect towards my [club] president, my board, not to bring to the public domain internal things.”
Mourinho also refused to speak about rivals Galatasaray, who are closing in on their third consecutive title.
He said: “I don’t speak about them,” he said when asked about Galatasaray on Sunday. “I speak about the championship and I’ve done it during the season.”
Mourinho had said in the past he was alarmed by what he called “a system” in the domestic league that is deeply ingrained.
“I don’t change one single word about what I’ve said during the season. One of the problems that Fenerbahce has is exactly the difficulty to cope mentally with the power of the system.
“It is something that is stronger than the quality…it is something really powerful. Players do feel it and they know it’s completely impossible to reach what they want to reach.”
Mourinho accepted that Fenerbahce have failed to live up to expectations this season, failing to beat any of their two major rivals, Galatasaray, and Besiktas.
He concluded: “It’s normal in this culture when results are not the results that people expect for there to be reactions,” Mourinho said. “I will never be critical of that. I’m open to critics, it’s part of my life.”
Up next for Fenerbahce is an away clash against Istanbul Basaksehir on Friday.
