He added at the time that he had to decide whether it was the right decision to promote Steve Davis and bring in a new coach rather than bring in a new assistant manager and after working with him for the last two weeks he's made his decision.
Cotterill said today: "I am pleased that Steve has accepted the post of assistant manager. I think that from the time he has been here, he has been absolutely first class. He is energetic and enthusiastic and has good ideas. I also think he does more than he needs to and thinks out of the box, which I like."
Steve Davis, who had three spells with the club as a player, returned initially as a scout in October 2005. He replaced Mark Yates as coach in January 2006, taking up his position on match day for the first time in the cup tie at Derby.
The manager added: "Steve deserves everything he's got. His career has gone very quickly from being a scout to a coach and now in his new role as assistant manager, but that is probably all credit to him for the way he has been, so I am very pleased.
"I don't want to make a big fuss on the role straight away because we needed to get on with things. We have obviously worked a lot closer together in the past couple of weeks and I just needed to hear his thoughts and how he reacted to mine within that period.
"I don't see any reason now to delay what I originally thought. I just wanted to have a look for myself before I made the decision because it is such a big one. Now I have done that and when I did decide, a couple of days ago, it was an easy decision to make."
This appointment will certainly prove a popular one with the Burnley fans. Steve Davis was always a hugely popular player during his time at Turf Moor, playing in three promotion sides and captaining the last one. His return as coach was very much appreciated by the supporters as will this latest appointment.
