Asked on Murphy's future, Bruce said: "Jacob has trained with us the last few days.
"He probably thinks to himself he hasn't had a fair crack of the whip.
"Certainly, I haven't seen a great deal of him. I'll be interested to see how he does.
"I know he had a really good spell at Sheffield Wednesday last year and did very well."
Bruce admitted: "They think the world of him. He did very, very well and would like him back, that's fair to say.
"I am going to take my time with him and have a look.
"We have plenty time with it to see what the next step is.
"He has had a successful loan and looks like he's developed a bit, so we will see what he will do."
