Phil Parkinson, arguably the most successful manager in Colchester United’s history, is poised to be named the new manager of Bolton Wanderers tomorrow.

The inspirational Parkinson, who guided the U’s into the Championship with an historic promotion from the third tier in 2006, stood down as Bradford City manager this afternoon.

The 48-year-old, who was the sixth longest-sering manager in the top four divisions, is expected to be unveiled as Bolton’s new boss tomorrow – the Trotters were relegated from the Championship last term,

Parkinson, whose first managerial job was with Colchester, from 2003 to ‘06, had been the boss at Bradford since the summer of 2011.

It is believed that Bradford and Parkinson have come to an agreement over the latter’s departure, with compensation to be paid by Bolton.

Parkinson left the U’s within a few weeks of propelling them into the Championship in 2006, to be appointed the new boss at Hull City.
