According to Michael Benson's twitter This fight is going to take place at the vodaphone arena in Istanbul, not not for 1 second do I believe this not at all but Benson is normally reliable. Kubrat Pulev apparently posted this on his Facebook. Anyway presuming this fight is next I don't foresee Joshua having any problems.
Pulev seems seriously past it. He was no joke back in the day. Now, he's a decent name but shouldn't be a serious threat. Then again....you knew know in HW boxing.
