Aldridge said: "It would be unfair to think we will win the league all of a sudden. We are so far behind teams like Arsenal, but we do want to see progress.
"Hopefully we will win a cup along the way and improve in the Champions League - that is an area where I would expect Benitez and Liverpool to do well.
"Benitez's track record is good. He said in his press conference that he has been looking at Liverpool videos, so he probably already has an idea what he needs to do in the transfer market. He will have to move quickly, though.
"He appears to have done his homework. I just hope the type of football he plays is exciting and his team will play the old Liverpool way. There must be an attacking fluency to our game, which we probably haven't had for a while."
