The former Chelsea coach is trusted by his players because they can see their hard work mirrored in him. He arrives at the training ground around 8am each day to plan the day's training with his coaches, even laying out the cones.
Defender Ashley Williams said: "He demands 100 per cent every day and he gives that himself, so you can't complain about his exacting standards. He is very organised, knows exactly what he wants at all times. That leaves no room for excuses.
"But he's not a sergeant major. We like him and we know we can always talk to him."
