Speaking about Fowler's return, Rush said it was a good move by Rafa Benitez which could see the Reds pick up an extra ten points this season.
"Of course, they say you should never go back. And, to be quite honest, the situation is not quite the same as when I returned after a year at Juventus," said Liverpool's all time record goalscorer.
"I like to think I was still in my prime whereas Robbie is 30 and not exactly a 90-minute player these days.
"But Rafa Benitez is not stupid. He knows Liverpool desperately need a finisher - never more so than last Sunday when they outplayed Manchester United at Old Trafford and still lost.
"Bring Robbie on for 20 or 30 minutes and he can make all the difference. The opposition know that as well.
"Robbie can give Liverpool an extra 10 points a season - the difference between finishing above or below United. Maybe even catching Chelsea."
