This broke late last night, European time:
"Everton and Fenerbahce are close to concluding a €3.5m deal for Joseph Yobo. Should be done in a matter of days." This was from Nigerian Journo Colin Udoh's twitter page. He is in the know with all the Nigerian players so it is to be trusted. As more has transpired today, I have also heard the offer could be €4.5 with the loan fee included.
*UPDATE* Looks like the offer of 3.5 mil Euro will be accepted after a personal plea from Yobo. It will shake out to be around 3.1 mil pounds. Apparently Yobo spoke with the club and made a personal plea for the transfer. Yobo has publicly stated that while he loved his time as a Blue, he has no intention of ever wearing an Everton shirt again. Best wishes to Yobo in all his future endeavors.
