The 30-year-old Nigeria international defender spent last season on loan in Turkey, and is hoping to stay there.
However, the Toffees are haggling over the fee as they believe they had agreed a 6million euros figure - only for Fenerbahce to offer around half that amount.
Now Yobo's former Super Eagles team-mate Okechukwu Uche, who also spent several seasons at Fener, has called on both clubs to sort out the move.
"Joseph is not having a good holiday as his future remain unresolved," said Uche.
"He had a wonderful season at Fenerbah?e, the management and fans would love for him to stay at the club and that is key.
"I hope both clubs can just consider the player's desire, ambition and happiness as only a happy man will give his best on the pitch.
"We've heard other clubs are also interested in Yobo, who haven't made official bids yet but the player has repeatedly stated his desire to play on at Fenerbahce."
Everton could be willing to deal at around 4million euros but until then, Yobo is having to sit tight.
