WILLIAM Kokolo revealed the chance to work with Jimmy Floyd Hasselbaink was a major factor in his decision to leave Middlesbrough for Burton.
The 21-year-old defender spent time on loan with National League North side Darlington last season, but had trained with Boro’s first team on a regular basis.
He featured in Boro’s FA Cup win at Mansfield, but is now fully focused on Burton.
Kokolo said: “I hope I can help the club to go forward. Jimmy was a big reason for me joining here.”
