Simpson, who is currently on loan from Manchester United, is impressed with the man who replaced Paul Ince as manager last month.
“He has just brought in his own ideas on the training pitch, and everyone has taken it on board,” said Simpson.
“He has got an aura about him. Everyone listens to him and respects him.
“Things are just clicking on the training ground, and from the training ground, it is carrying on to the pitch on a Saturday.
“We have always said we were a team that should be doing well, and now we are doing well and hopefully we will take that into the game [at Fulham] on Saturday.”
