Mick Harford becomes number two, Tim Breacker first team coach
Speaking about the appointment of Mick Harford, Steve said: "I'm delighted that Mick has joined us. He's a vastly experienced coach who I have known for many years now.
Mick will be a great addition to the staff and I'm pleased to have finalised my backroom team, with Kevin Pressman continuing as the goalkeeping coach as well.
I know there was speculation about Mick going to Newcastle because of his past connections with Joe Kinnear, but he's fully committed to Millwall and to doing a job for us here."
