5. James DeGale
Golovkin is a force at middleweight, his 21 consecutive knockouts are testament to his power. Though aggressive he is also a quality technician, just look at his use of footwork and the jab last weekend. Golovkin may not the biggest middleweight but his qualities are surely enough to carry him out of his natural division, and with James DeGale the leading super-middleweight champion at the moment, he would be a natural opponent at 168lbs.
