Port Vale have confirmed Micky Adams' departure to take charge at Championship club Sheffield United.
Sheffield-born Adams, a self-confessed Blades fan, has signed a two-and-a-half year contract at Bramall Lane after personal terms were agreed on Thursday along with a confidential compensation package for Vale.
Adams turned Vale`s fortunes around during his year and a half at the helm and chairman Bill Bratt, who described the compensation as "appropriate", is desperately disappointed to see him leave.
Adams himself said: "I've had a fantastic 18 months at Vale Park and I genuinely hope Port Vale do well this season and beyond, as the club deserves success. I don't have a bad word to say about anyone here and I have never actively pursued a route out of the club.
"This was an incredibly difficult decision for me - probably more difficult than many could imagine. I've made no secret of my desire to manage Sheffield United at some stage in my career and that time has arrived now. That is no reflection on anyone at Port Vale - Vale Park is full of fantastic, committed people and the backing I have had from the supporters has been nothing short of phenomenal."
Geoff Horsfield and Mark Grew will step up to the role of joint caretaker managers for Saturday`s trip to Rotherham.
