Bruce was speaking after defeat to Preston North End on Saturday.
Asked about the fans, Bruce said: "No, as I have said I won't everybody's cup of tea. I am certainly not Rafa Benitez that is for sure.
"Whoever would follow in his footsteps would find it difficult. I am delighted to be here.
"I will go to work again tomorrow. Physically we can still be better.
"We still have a big couple of weeks. I might have been in that stand myself today.
"But that rain would test my loyalty!
"Standing in this weather on a trip over to Preston would be tough but I might have been one of them.
"I wasn't quite good enough at 13 or 14 as a player for them but I will try to do my best now (as head coach)."
