Manager Paul Lambert has left the U's to become the new manager of Norwich City.
Lambert resigned as manager of the U's last night to take up the post at Carrow Road this morning, after U's Chairman Robbie Cowling failed to agree a compensation package with Norwich City.
Assistant manager Ian Culverhouse has also quit the club along with Operations Manager Gary Karsa.
U's (and Gills) legend Joe Dunne will take caretaker charge of the first team for tonight's home game against Gillingham.
