It is all part of the new policy at Norwich of ensuring all members of the coaching staff are former Norwich players, and new manager Bryan Gunn said today: "I'm delighted to bring Paul to my backroom staff.
"I've known him from his time at the club when he was understudy for Robert Green. He like the rest of the coaching team knows the club and I think that's important. We want someone to continue to develop not only the first team goalkeepers but those in the academy and I know he's looking forward to putting a development programme in place which is important as we've had a good record in this position in recent years."
Crichton said on his return: "I am delighted to be coming back to Carrow Road. I had three great years here, ending in the Championship winning season. I didn't play many games but I just wanted to return, it's a great place.
"The club is in a false position at present, and if I can help support the gaffer, support the goalkeepers, support the club as a whole, then I want to do so. I want the club to be back where it belongs."
